HANDGUN AMMUNITION

RIFLE AMMUNITION

BRASS

The 32 ACP auto inhabits a valuable and useful place in our society as a defensive cartridge, mostly because of the easily concealable, tiny pistols chambered for it. HOWEVER, because of the very limited size of the cartridge, it is plagued with limited power and therefore most of the existing ammo in 32 ACP suffers from not being reliable as a man-stopper. We’ve studied and examined nearly all available 32 ammo and find it wanting as a reliable means of self defense, especially against a large, drugged up/pain free, determined attacker.

Here’s the problem. The current 32 ACP frangible ammo delivers a large amount of surface trauma, but lacks sufficient penetration. For example, if you shot me or another sane man in the face, with modern, frangible 32 ACP ammo, it would blow off a big portion of my cheek. I would undoubtedly fall to the ground in shock and pain, but I would be very much alive and functional if I could get past the pain, as that frangible bullet would have stopped somewhere in my face, never making it to my brain. However, if you shot a drugged up maniac in the face with that same frangible bullet and blew half his cheek off, he would keep right on coming because he is insane and is not thinking like you or I. Plus, he is likely pain free and fear free and wont know that part of his cheek is missing and if he did know, he would not care. So, whatever 32 ACP ammo you shoot him in the face with, had better go through his face and blow his brain stem out the back of his head, because only a CNS (central nervous system) hit with a 32 ACP is going to stop him. Likewise, a torso hit to the sternum needs to penetrate deep enough to blow all the way through his spine in order to shut him down instantly. If you fail to shut him down instantly, you and your loved ones are going to have to find a way to survive while you wait for him to bleed out and pass out. The best chance of survival for you and your loved ones, is to shut down the attacker instantly. So, we’ve designed this 32 ACP+P load to keep you and yours alive under the worst of scenarios.

This 32 ACP+P  ammo will better all American made 32 ACP+P  ammo by 110 fps to 150 fps with a heavier bullet than any other American made 32 ACP ammo.

1.       Item 30A/20 is a 75gr. HARD cast bullet with a flat nose. It is traveling over 1,000 fps out of my 3.4 inch Beretta Mod. 70. We’ve used a flash suppressed powder so that you won’t be blinded by your own gunfire in the dark. This is significant as well over 90% of all civilian shootings in America occur in low light when the criminal element is out and about.  Also, this flat nosed, nonexpanding, hard cast,  bullet  will penetrate deeply and will do much more damage than the typical round nosed FMJ bullet. Round nosed bullets tend to slip and slide through living tissue, doing little damage as opposed to a flat nosed bullet. The flat nose not only wounds much more than a round nosed bullet, but it actually keeps the penetration straight and thus deeper. Notice the below velocities from my personal 32 ACP pistols. These are real world guns and thus the speeds are realistic  and not the exaggerated speeds you’ll see produced from laboratory test barrels. What you see with Buffalo Bore Ammo advertising, is truly what you get in the “real world” where it matters. You can expect 20+ inches of straight line penetration in flesh and bone with this load. If you are worried about over –penetration with this load, DON’T! You chose to carry a tiny under-powered 32 ACP pistol and the trade off is that now you are going to have to stay alive using this pistol and over-penetration will be the least of your worries if you end up needing this gun to save yourself or your family.

A.     Berretta Mod. 70, 3 inch bbl.— 1001 fps

B.     Kel Tek, 2.5 inch bbl—910 fps

C.     Seecamp, 2 inch bbl.—856 fps

The above bullet speeds are 110 fps to 150 fps faster than the Winchester 71 gr. FMJ ammo on the American market.  Not only is our bullet heavier than any other American made 32 ACP ammo, but it is moving about 15% to 20% faster—with that heavier bullet!

The 380 auto inhabits a valuable and useful place in our society, mostly because of the easily concealable, tiny pistols chambered for it. HOWEVER, because of the very limited size of the cartridge, it is plagued with limited power and therefore most of the existing ammo in 380 auto suffers from not being reliable as a man-stopper. We’ve studied and played with nearly all of the existing available 380 ammo and find it wanting as a reliable means of self defense, especially against a large, insane, drugged up/pain free, determined attacker.

Here’s the problem. The current 380 auto frangible ammo delivers a large amount of surface trauma, but lacks serious penetration. For example, if you shot me or another sane man in the face with modern frangible 380 ammo, it would blow off a big portion of my cheek and send a few teeth down my throat, I would undoubtedly fall to the ground in shock and pain, but I would be very much alive and functional if I could get past the shock and pain as that frangible bullet would have stopped some where inside my face, never making it to my brain. However, if you shot a drugged up maniac in the face with that same frangible 380 ammo and blew half his cheek off, he would keep right on coming because he is insane and is not thinking like you or I. Plus, he is likely pain free and fear free and wont know that half his cheek is missing and if he did know, he would not care. So whatever 380 ammo you shoot him in the face with, had better go through his face and blow his brain stem out the back of his head, because only a CNS (central nervous system) hit with a 380 is going to stop him. Likewise, a torso hit to the sternum needs to penetrate deep enough to blow all the way through his spine in order to shut him down spontaneously. If you fail to shut him down instantly, you and your loved ones are going to have to find a way to survive while you wait for him to bleed out and pass out. The best chance of survival for you and your family is to shut down the attacker instantly. So, we’ve designed a few 380 auto +P loads to keep you and your loved ones alive under the worst of scenarios.

This 380 Auto+P ammo will better all American made 380 Auto ammo by 150 fps to 200 fps in all bullet weights we make. This is a serious improvement in this typically anemic cartridge. This 380 auto+P ammo is more powerful than the typical 38SPL ammo made by most American ammo makers and you’ll get 7 shots of it in a small/flat/light weight 380 versus 5 shots out of a bulkier 38 SPL J frame revolver. Additionally, with the 380 you’ll get much faster reloads and the little magazines are flatter than a speed-loader used for a J frame.

1. Item 27A/20 is a 100gr. HARD cast bullet with a flat nose. It is traveling over 1,150 fps out of my 3.75 inch BDA (Browning Double Action). We’ve used a flash suppressed powder for all three of our 380 auto loads so that you wont be blinded by your own gunfire if you have to shoot in the dark and since around 95% of all civilian shootings in America occur in low light, the chances that your own gunfire will blind you while you are trying to save your life, are good—we’ve eliminated this variable by using flash suppressed powder. We’ve also chosen a flat nosed solid bullet. The flat on the nose ensures that the bullet will cut/smash its way through flesh and bone and do much more destruction than typical round nose FMJ bullets. Round nosed bullets tend to slip and slide through matter, doing little damage as opposed to a flat nosed bullet. The flat nose not only wounds much more than a round nosed bullet, but it actually keeps the penetration straight and thus deeper. Notice the below velocities recorded from my personal 380 auto pistols. These are real world guns and thus the speeds are realistic and not exaggerated speeds produced from laboratory test barrels. What you see with Buffalo Bore Ammo, is truly what you get in the “real world”, where it matters. You can expect 20+ inches of straight-line penetration in flesh and bone with this load. If you are worried about over penetration with this load, DON’T! You chose to carry a tiny under-powered 380 auto pistol and the trade-off is that you are now going to have to stay alive with that pistol and over penetration will be the least of your worries if you end up needing this gun to save yourself or your family.

1. BDA-3.75 inch barrel--- 1160 fps
2. Walther PPK-3.5 inch barrel-----1149 fps
3. Colt Mustang Pocket Lite-2.75 inch barrel---1072 fps
4. Keltec---1061 fps

2. Item 27B/20 is the very same load as 27A above, but it uses a 95 gr. FMJ-FN (Full metal jacket-flat nose) bullet. We designed it for folks who simply don’t like hard cast bullets. Although it is 5 grains lighter, it is moving a tad bit slower than the 100gr. hard cast bullet. This is because the hard cast bullet produces less friction in the barrel than a jacketed bullet and therefore produces less pressure, so we can run it a little faster even though it is heavier. Some pistols may not give good accuracy with the cast bullet, and some folks don’t like cast bullets, so we made the same load with a jacketed bullet for those folks. This FMJ-FN load is designed to do the very same thing as the hard cast load above. Check out my “real world” velocities from my “real world” pistols below. You can expect nearly 20 inches of straight-line penetration in human flesh and bone with this load.

1. BDA-3.75 inch barrel----1145 fps
2. Walther PPK-3.5 inch barrel----1120 fps
3. Colt Mustang Pocket Lite-2.75 inch barrel----1042 fps
4. Keltec—2.75 inch barrel----1019 fps

3. Item 27C/20 is a 90gr. Speer Gold Dot (Unicore) bullet and is the only hollow nosed expanding bullet we trust to expand reliably, yet penetrate deep enough to be lethal on a drugged up, pain free attacker. It is traveling over 1,200 fps out of my BDA (Browning Double Action) with its 3.75 inch barrel. This bullet is truly bonded and will mushroom to about .55 caliber and not lose any weight, thus penetrating quite deeply in human matter. You should expect about 10+ inches of penetration in flesh and bone. We’ve utilized the very same flash suppressed powders that we’ve used in our two other 380 auto +P loads. If you like the idea of the extra big hole this expanding load makes in human flesh, we would advise that you load this bullet in your chamber, followed by a magazine full of our non-expanding loads. So, if the first shot does not incapacitate the attacker, your magazine is full of ammo that will, if you can put the bullet in his spine or brain from any angle. Note my “real world” velocities from my personal “real world” pistols.

1. BDA-3.75 inch barrel----1218 fps
2. Walther PPK-3.5 inch barrel-----1200 fps
3. Colt Mustang Pocket Lite-2.75 inch barrel---1123 fps
4. Keltec---1100 fps

All Buffalo Bore 9mm +P and +P+ ammunition is loaded with flash suppressed powder so you won't be blinded if you have to drop the hammer in low light. Over 90% of all human shootings are in low light, so flashed suppressed powder can be a life saver as no one wants to be blind after they fire one shot in a real critical situation.

There is such a variety of 9mm pistols in public use that we will not determine what guns are compatible with which 9mm loads. It is up to you to determine the compatibility of any ammo with your particular pistols.

Check out the below velocities that we shot with our ammo in several modern pistols. We don’t believe that test barrels are a very real way of determining the true velocities of ammo out of real guns. So, as with all of our ammo, we use real firearms to determine real velocities.  Note that the longest barrel did not generate the highest velocities with any load. This suggests that there are a lot more factors involved with velocities in internal ballistics than just barrel length.

All Buffalo Bore Heavy 40 S&W +P loads use flash suppressed powders that give high velocities at low pressures. Since over 90% of all human shootings in the USA happen in low light, we believe that flash suppressed powders are a potentially life saving advantage—you don’t want to be blind after you fire one shot in a life threatening, high stress situation.

There is such a variety of 40 S&W pistols in public use that we will not determine what pistols are compatible with which 40 S&W +P loads—this is your responsibility! We will add that this ammo is safe in pistols that use a fully supported chamber. Please read the safety notices below. The first one is taken form the Speer #13 loading manual. The second is taken from Hodgdons #27 loading manual.

SAFETY NOTICE

“Some pistols chambered for the 40 S&W cartridge may not provide complete support of the case head. If this condition exists, normal pressure loads such as those shown here can cause the case wall to bulge or rupture at the unsupported point. Contact your firearm manufacturer to determine if your pistol completely supports the case head, or ask a gunsmith to inspect your pistol before using it with ANY ammunition. It is the gun owners responsibility to know his firearm and its capabilities and limitations.”

40 S&W WARNING

“This data is intended for use in firearms which fully support the cartridge in the chamber. Use of this data in firearms which do not fully support the cartridge may result in bulged cases, ruptured cases, case head separation, or other conditions which may result in damage to the firearm and/or result in injury or death of the shooter or bystanders.”

Glock happens to chamber their 40 S&W pistols without a fully supported chamber and both of those above safety notices are likely aimed at Glock. I know of no other 40 S&W handguns being sold in the US that don’t have fully supported chambers. If you really want to shoot our 40S&W ammo in your Glock, have an after market barrel that uses a supported chamber, dropped into it. This is a fairly common practice and will give you the safety margin needed to fire our ammo in your Glock. It will also likely give you more velocity that the factory Glock barrel. I personally own two Glock Model 23’s. Both of mine are going to get after market barrels dropped in so that I can use this excellent ammo in them.

Check out the velocities below that I shot with these loads in several modern pistols that I own. We don’t believe that test barrels are a very real way of determining real life velocities out of real life guns that you will be using. So, as with all of our ammo, we use real firearms to determine real velocities.

1. Item 23A/20: 155gr. Speer Uni Core 

a. Custom made 1911 with Nowlin (5inch barrel) = 1318 fps
b. Taurus PT 100 (4.9 inch barrel) = 1249 fps
c. Sig 229 (3.75 inch barrel) = 1221 fps

About Buffalo Bore 10mm ammo

The Buffalo Bore Heavy 10 mm ammo is the result of several years of customers request that we produce two such loads for the 10 mm.

Both velocities are taken from standard 5 inch 1911 type pistols. These loads bring out the full potential of the 10mm, but operate at standard pressures and as such, are safe to use in any standard 10mm pistol. Please don't phone us and ask if these loads are safe in your 10mm--THEY ARE--provided your 10mm is a normal operating pistol in good condition.

We are using flash-suppressed powders so your vision will not be materially affected should you be required to drop the hammer in low light.

If you are firing this 10mm ammo from an autoloader and experience high extreme spreads in velocity, it is not the ammo. Here is why and how to remedy the situation.

Full power 10mm ammo has always generated enough recoil and pressure to require a pretty stiff recoil spring in your handgun—this of course depends on several variables such as your slide weight, etc. When the cartridge fires, it generates enough pressure/recoil to prematurely open your breech face in some guns. When this happens, the opening breech face has an effect on the burn rate of the powder. This can result in some fairly high extreme spreads in velocity. If you are experiencing extreme velocity spreads of more than 50 fps, simply install a stiffer recoil spring. For example, I have an original Colt Delta Elite. This gun with the factory spring runs extreme spreads of about 35fps with both of these 10mm loads. I am happy with 35 fps, so I leave the Delta Elite as is. I also have a custom built Para Ordinance with a Nowlin barrel. It runs extreme spreads of about 70 fps with its original recoil spring. When I install a spring that is 4 lbs stiffer, the extreme spread drops to about 35 fps. The new Glock model 20 comes with a recoil spring that allows the breech face to open too soon and my new Glock model 20 will get extreme spreads of about 100fps with the factory spring installed. When I go to a stiffer recoil spring, the extreme spreads drop to about 50 fps in my new Glock model 20. Of course none of this will be an issue in a revolver. None of this will be an issue in real life either, as these high extreme spreads don’t hurt accuracy or function. However, I mention this because if you are like me and want things to be as correct as possible, I have outlined the problem and the solution. The industry fixed all these problems initially, by watering down the 10mm ammo over the last several years. The watered down 10mm ammo does not generate the pressure/recoil to open the breech face early. If you want the full powered 10mm ammo we make, you simply need to tweak your pistol. Or just realize that you are getting some fairly high extreme spreads and ignore it or live with it. It’s not hurting any thing in reality.

Please understand that we get hundreds of emails per day. If we don’t answer your email, it is not because we don’t value your patronage, but it is because we simply don’t have the manpower to answer so many emails. Thank you for your business. Have fun and be safe.

About Buffalo Bore Heavy .38 Special +P ammo

The new Buffalo Bore Heavy 38 SPL+p ammo will maximize the effectiveness of your 38 SPL revolver.  The powders are flash suppressed so as to not hinder your vision should you be required to drop the hammer in low light.

Item 20A/20 is the terrific SOFT lead semi wad cutter hollow cavity bullet, however we've added a gas check to stop the leading that this load typically causes with other manufacturers version of this bullet.

Item 20B/20 uses the low velocity (LV) Gold Dot bullet that is designed to expand at as little as 800 fps, so you will get expansion out of very short barrels.

Whether you prefer the very soft semi wadcutter lead bullet, or a very soft JHC, (jacketed hollow cavity) these HVY 38 SPL+p loads will turbo charge your 38 SPL revolver.

The tactical reload: Short (2 to 2.5 inch) barreled revolvers have short ejectors. Those short ejectors typically used on 2 inch to 2.5 inch barreled revolvers are not long enough to fully eject 357 magnum brass. So if you are forced into a situation where you need to reload your weapon under fire, you will find yourself picking your fired/empty 357 brass out of the cylinder one at a time—this is very bad. On the other hand, 38SPL brass is shorter than 357 brass and those short ejectors will often fully eject 38SPL brass. We have experimented a great deal with short barreled revolvers and have found that 38SPL brass normally offers an advantage if you need to reload your “snub nose” revolver, in a hurry.

Check out the below velocities that I fired from my personal revolvers. We believe that real world, stock, “over the counter” guns, give real world results, so we don’t advertise velocities that are fired from long test barrels.

These 38SPL+P loads are generating low-end 357 magnum, ballistics. If you have an older or more fragile 38SPL, or if you are recoil sensitive, consider using our HVY Standard Pressure 38SPL ammunition. It is safe to be fired in any 38SPL revolver and it still packs much more punch than ordinary 38SPL ammo.

Item 20A: 158gr., very soft cast, semi wad cutter, (Keith) hollow cavity, with a gas check. This bullet will mushroom violently on impact and will penetrate roughly 14 inches in human flesh. Again, this bullet is gas checked and will not lead your barrel.

S&W mod. 60, 2 inch—1040 fps (379 ft. lbs.) 
S&W mod. 66, 2.5 inch—1059 fps (393 ft. lbs.) 
Ruger SP101, 3 inch—1143 fps (458 ft. lbs.) 
S&W Mt. Gun, 4 inch—1162 fps (474 ft. lbs.) 

Item 20B: 125gr. Speer Uni-core (Gold Dot). This is the Low velocity version designed to expand under 800 fps. It will mushroom violently and penetrate roughly 12 inches in human flesh.

a. S&W mod 60, 2 inch—1072 fps (319 ft. lbs.)
b. S&W mod 66, 2.5 inch—1108 fps (341 ft. lbs.)
c. Ruger SP101, 3 inch—1180 fps (386 ft. lbs.)
d. S&W Mt. Gun, 4 inch—1258 fps (439 ft. lbs.)

Standard Pressure, Short Barrel, Lower Recoil,  Heavy 38 SPL  

Due to customer demand, we’ve developed this defensive 38SPL ammo. Our customers wanted some devastating 38SPL loads that would fill the following criteria. 

1. It won’t hurt older/fragile/alloy revolvers. (Non +P)
2. Is effective as a “fight stopper” through the use of proper bullets. 
3. Is more powerful than typical/standard, weak 38SPL ammo.
4. Generate much less recoil than our +P 38SPL ammo.
5. Is flash suppressed.

Buffalo Bore is introducing these three different heavy, yet standard pressure loadings for 38 SPL. These offerings are loaded at standard pressure, but they are much more powerful than normal 38SPL ammo. These loads will not harm older more fragile revolvers. So, these loads are safe for use in ANY 38 SPL revolver, provided it is in normal working condition. As stated above, the “POWER” level of these loads is really closer to a typical +P power level, but the pressure is standard.  We are able to develop these powerful standard pressure loads with modern non-canister powders. Again, these loads recoil far less than our +P 38 SPL ammo. 

All three of these loads are flash suppressed, so firing them in the dark wont blind you. We use flash suppressed powder in our defensive ammo, in the loadings we can, because over 90% of all civilian shootings in America, occur in low light, when the criminal element is at work. We don’t want you blinded by your own gunfire after the first shot. 

Item 20C utilizes the same 158gr. very soft lead cast, SWC-HC gas checked bullet, we load in our +P 38 SPL ammo. It is designed to expand and then penetrate quite deep. (Approx. 14 inches in human tissue) This bullet is gas checked and will NOT lead your barrel. Note the below velocities that I recorded out of my personal revolvers—NOT TEST BARRELS!

1. S&W mod. 60, 2 inch barrel—854 fps (256 ft. lbs.)
2. S&W mod. 66, 2.5 inch barrel—871 fps (266 ft. lbs.)
3. Ruger SP101, 3 inch barrel—930 fps (303 ft. lbs.)
4. S&W Mt. Gun, 4 inch barrel—979 fps (336 ft. lbs.)

Item 20D utilizes a very hard cast 150gr. WAD CUTTER bullet. The bullet is made hard, so it won’t deform or mushroom. It cuts/crushes a “cookie cutter”, full diameter hole in human flesh just like it does on a paper target. It penetrates deeply (roughly 14 to 16 inches in human tissue) and its full diameter profile maximizes blood loss as it cuts and crushes (not slips or slides) its way through tissue. Although I’ve never been shot with a full profile wad cutter bullet, I must assume that the initial impact of that wide flat nosed bullet, is crushingly formidable. As a teenager, I took to the woods on a regular basis and killed many a critter with heavily loaded 38SPL wad cutters’.  The effect of a full profile wad cutter on small game was obvious and amazing, compared to regular round nosed bullets. That flat nose, literally hammers living things. These bullets are hard and properly lubed and will NOT lead your barrel. Note my velocities from real world “over the counter” revolvers—NOT TEST BARRELS!

  a. S&W mod. 60, 2 inch barrel—868 fps (251 ft. lbs.) 
  b. S&W mod. 66, 2.5 inch barrel—890 fps (264 ft. lbs.)
  c. Ruger SP101, 3 inch barrel—961 fps (308 ft. lbs.)
  d. S&W Mt. Gun, 4 inch barrel—1005 fps (336 ft. lbs.)

Item 20E utilizes a Speer Low Velocity uni-core (Gold Dot) 125 gr. Jacketed hollow nose bullet. This bullet is designed to expand at low speeds and has no problem opening up at considerably less velocity than our advertised 900 fps, from two inch barrels. Penetration in human tissue is roughly 12 inches. Note my test velocities below from real world, “over the counter” revolvers—NOT TEST BARRELS!

1. S&W mod. 60, 2 inch barrel—921 fps (235 ft. lbs.)
2. S&W mod. 66, 2.5 inch barrel—938 fps (244 ft. lbs.)
3. Ruger SP101, 3 inch barrel—1019 fps (288 ft. lbs.)
4. S&W Mt. Gun, 4 inch barrel—1078 fps (322 ft. lbs.)

About Buffalo Bore 357 Mag. ammo

Our 357 mag. ammo adds more power than ever before to the 357 mag. This ammo is safe to shoot in ANY all steel 357 revolver—this includes J frames. This ammo is no harder on your gun than any other normal 357 ammo. Please don’t phone us and ask if this ammo is safe in your gun. It is, providing your gun is in safe condition for use with any normal 357 ammo.

We don’t recommend this ammo to be fired in super light alloy revolvers as bullets may jump crimp under recoil, but the ammo itself wont hurt these super light weight revolvers. These revolvers are simply so light that the recoil is severe enough to cause crimp jump.

The below velocities are offered so that you can see what guns/barrel lengths give what velocities with this new 357 mag. ammo. You’ll notice that new S&W revolvers with short barrels are often shooting faster than older S&W revolvers with longer barrels. The new S&W revolvers are very good and are made with equipment that makes them more consistent and faster than the S&W revolvers of yesteryear.

Make special note of the Marlin 1894, 18.5 inch barrel velocities. Item 19C/20, supercedes 30-30 energies!!!

Tactical Short Barrel, Low Flash, Reduced Recoil 357 Magnum

Printed Order Form

Buffalo Bore’s new Tactical Short Barrel, Low Flash, Reduced Recoil 357 Magnum

Typical full power 357 magnum loads offer several tactical problems for use in self defense and duty applications, especially when used in the shorter/lighter revolvers that are typical of concealed, defensive and duty carry. First, the muzzle flash can be blinding, especially from short barrels. Second, felt recoil can be a life-threatening drawback if fast follow-up shots are required. Third, the level of report can be deafening and cause permanent hearing loss, especially if fired indoors.

All three Buffalo Bore Tactical Short Barrel loads address the above problems and make the 357 magnum ideal for concealed, defensive and duty carry in smaller revolvers.

Muzzle flash: These exciting new 357 magnum loads utilize a flash suppressed powder that will not blind you, should you need to drop the hammer in a low light situation. It is estimated that over 90% of all defensive civilian shootings in the U.S. happen in low light—that is when the criminal element is at work. Wouldn’t it be horrible if you fired at an assailant, in the dark, to protect your family, only to find that you missed the bad guy and you are now blind due to your own muzzle flash? This is a scenario that has happened many times in the real world with the 357 magnum. Through the use of our non-canister, flash suppressed powder, the tactical problem of blinding muzzle flash is now greatly reduced with Buffalo Bore’s new Tactical Short Barrel loads! 

Recoil: Felt recoil is exacerbated by the use of shorter barreled, smaller framed, lighter weight 357 revolvers, typically used for concealed and duty carry. The new Buffalo Bore Tactical Short Barrel 357 loads are not the normal full power “barn burner”, 357 magnum loads we make and as such, felt recoil is substantially reduced, although they remain very powerful. Hence, deadly, and faster follow-up shots are more possible. 

Your ears: Most folks don’t think of the level of “report” as being a problem during a life threatening/defensive shooting and that may be correct for the actual moment of conflict. However, to lose some of your hearing for the rest of your life, following the shooting incident, is unnecessary and undesirable. Full power 357 magnum ammunition is deafening, even more so when fired from short barrels and even worse if you are required to shoot from an enclosed area such as a vehicle or indoors. Buffalo Bore’s Tactical Short Barrel 357 magnum loads are not as hard on your hearing as full power ammunition. Although the use of hearing protection is still desirable, if possible, when using this ammo. 

For those who wish to carry a 357 magnum revolver for potential “conflict resolution”, these new Buffalo Bore loads put an end to the “tactical” draw backs associated with our regular 357 magnum ammo. These loads are great for use in longer barreled firearms too.

Special Information Note: The below velocities were obtained from my personal, real world, factory stock, over the counter, (NOT TEST BARRELS) 357 magnum, revolvers. Also, note that the 6 inch Python, is considerably slower than the 4 inch S&W. This has nothing to do with barrel length. It is most likely a combination of differences in chamber/throat dimensions, barrel-cylinder gap, barrel internals, and forcing cone dimensions in the Python, versus the S&W. If the Python and the S&W had the same dimensions in their chamber/throats, barrel cylinder gap and forcing cone, the longer barreled Python would give much faster speeds. We have found that all of our Python test revolvers are much slower than our late model S&W revolvers of equal or even shorter barrel length.

We could have reduced the recoil, flash and blast even more by “watering down” these loads further than we did, but then you wouldn’t have a real 357 magnum in your hands. So we looked for and found a balance between very powerful, fight stopping ammo that recoils and flashes much less than ours and some other makers, full power 357 loads. If we were to “water down” this “Tactical Short Barrel” 357 ammo any more, we would simply not manufacture it and suggest that you use our 38 SPL+P ammunition.

None of these loads caused crimp/bullet jump (in five shots) in my 12 OZ. Scandium S&W Model 340, but they did generate considerable felt recoil.

Item 19E/20—158gr. Speer Uni-core, (Gold Dot) hollow cavity, bullet @ 1,100fps from a 2.5 inch barrel. It is designed to mushroom, yet hold together and penetrate deeply—roughly 13 to 15 inches in human tissue. 

S&W mod. 340PD 1-7/8 inch barrel—1,015 fps (361 ft. lbs.)
S&W mod. 66 2-½-inch barrel—1,097 fps (422 ft. lbs.)

S&W Mt. Gun 4-inch barrel—1,232 fps (532 ft. lbs.)
Colt Python 6-inch barrel—1,198 fps (503 ft. lbs.)

WARNING—shooting this ammo out of revolvers weighing less than 16 OZ. produces tremendous felt recoil. We recommend our +P 38 SPL ammo for revolvers that weigh less than 16 OZ., if you are recoil sensitive.

Item 19F/20—140gr. Sierra JHC bullet (jacketed hollow cavity) @ 1,150 fps from a 2.5 inch barreled S&W mod. 66. Designed to mushroom and penetrate deeply—roughly 12 to 14 inches in human tissue. 

S&W mod. 340PD 1-7/8 inch barrel—1,088 fps (368 ft. lbs.)

WARNING—shooting this ammo out of revolvers weighing less than 16 OZ produces tremendous felt recoil. We recommend our +P 38 SPL ammo for revolvers that weigh less than 16 OZ., if you are recoil sensitive.

Item 19G/20—125gr. Speer Unicore (Gold Dot) bullet @ 1,225 fps from a 2.5 inch S&W mod. 66 barrel. Designed to mushroom violently, yet hold together and penetrate deeply—roughly 12 to 14 inches in human tissue. 

S&W mod. 340PD 1-7/8 inch barrel— 1,109 fps (341 ft. lbs.)
S&W mod. 66 2-½-inch barrels—1,225 fps (416 ft. lbs.)

About Buffalo Bore .357 Sig

Because you requested it, Buffalo Bore is now producing two full power 357 Sig. loads. These loads are full power 357 Sig. Not the watered down stuff that other factories are already producing. Why is it that a new cartridge gets developed with touted ballistics in the media, only to have the ammo manufacturers “water” it down after a few years on the market? (The same thing happened with the original 10MM) The 357 Sig. was designed to blast a 125gr. bullet at 1,425 FPS out of a four inch carry gun barrel. (Not a much longer test barrel) So, that is what both our loadings do.

We use flash suppressed powder so that you wont be blinded by your own gun fire should you be required to drop the hammer in low light. Since over 90% of civilian shootings in America happen in low light, flash suppressed ammunition is a huge tactical advantage.

Item 25A utilizes the 125gr. Speer Uni-core JHC (Gold Dot) bullet. It is designed to open radically and penetrate roughly 12 to 14 inches in human tissue. Note my velocities from my real world pistol, (not a test barrel) below.

a. Sig. Mod. 229, 4 inch barrel—1,430 fps (567 ft. lbs.)

Item 25B utilizes a 124gr. FMJ flat nose bullet at 1,425 fps. This bullet will smash through typical stick frame walls, car doors and a bears skull or shoulder bones. It is designed for those who need deep penetration. It should penetrate 24+ inches in human tissue. If I were carrying a 357 Sig. for defense, I would carry my pistol with our 125gr. Uni-core JHC (jacketed hollow cavity) loaded in the chamber and the top 4 or 5 rounds in the magazine. The remaining rounds in the magazine would be these FMJ flat nose loads. Why? After the first few rounds are fired in a fight, most opponents will be dead or behind cover. The FMJ flat nose loads will penetrate many types of cover that would stop a hollow nose bullet. Note my velocities, from my real world pistol, (not a test barrel) below.

a. Sig. Mod. 229, 4 inch barrel—1,433 fps (575 ft. lbs.)

All of today’s standard 45 colt loads are very anemic. Often featuring a 250 gr. Bullet at around 700 fps.

We knew that we could develop a couple standard pressure 45 colt loads that would feature a 255gr. Gas checked soft cast bullet at around 1,000 fps or a 200gr. JHC (Speer low velocity Gold Dot) at around 1,100fps. We wanted loads that were substantially more powerful than today’s weenie loads, but that could be fired in ANY 45 colt firearm.

Both of these 45 colt loads are designed to be a heavy loading, yet be within standard (SAAMI) pressure. As such, both of these 45 colt loads are safe and recommended to be used IN ANY post-war 45 colt that is in normal working condition. ANY post-war means ANY post-war, so please take my word for it without phoning or emailing me “just to make sure”. I love hearing from and appreciate customers, I really do, but there is no sense using up your or my time answering questions that have already been answered.

These loads are indeed heavy 45 colt loadings. You can fire them in any post-war firearm that is in normal working condition chambered for 45 colt without reservation. These loads will turn your Colt SAA or clone into a powerful carry gun. The cast load (item 3E) is gas checked and will not substantially lead your barrel. 

See the below velocities.

There have been several requests for a full power 44 mag. Load that recoils substantially less than our other Heavy 44 mag. Loads, but will still penetrate deeply and be deadly on game animals.

When S&W introduced their model 329PD, we noticed that some of those scandium revolvers would experience sticky extraction with our Heavy loads and the recoil in the light weight scandium 329PD guns was horrendous, to say the least. This recoil would some times cause bullets to “jump crimp” thus tying up the revolver. 

In order to alleviate the recoil, crimp jump and sticky extraction, we have developed this load. It is still full power, but uses a lighter weight, super hard cast, gas checked bullet and will still penetrate very deeply in big game despite its lighter weight. This load is ideal for those of you who carry the S&W model 329PD. This load will not lead your barrel.

This load falls well under SAAMI pressure specs and is safe to use IN ANY 44mag. While we love to hear from our customers, please do not phone/email us and ask if this load is safe in your particular 44 mag.—it is—providing your gun is in normal working condition.

Now there exists a serious full power 44 mag. load that will penetrate big bones (including a bears skull) and drive deeply into living organs and tissues, that has minimum recoil.

See the below ballistics fired out of my personal revolvers.

S&W 329PD (4 inch)---1264 fps

Ruger Red Hawk (5.5 inch)---1357 fps
