HEAVY 357 MAG OUTDOORSMAN
180 gr. Hard Cast LFN-GC (1,400 fps/M.E. 783 ft. lbs.)
20 Round Box
ITEM 19A
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 or email us and ask if this ammo is safe in your gun. It is, providing your gun is in a safe condition for use with any normal 357 ammo.
We don't recommend this ammo be fired in super light alloy revolvers as bullets may jump crimp under recoil, but the ammo itself won't hurt these super light weight revolvers. These revolvers are simply so light that the recoil is severe enough to cause jump crimp.
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 supersedes 30-30 energies!!!

Was camping near Pahrump Nevada and had a run-in with a rather desperate coyote that was far too comfortable with humans. After scaring him off a third time he decided to try and take a bag right off my niece's lap. Fed up, I took a shot with my lcr loaded with these hardcasts.
Let me first state that I know these are loud. I never questioned it. I've shot them with ear protection on numerous times. We were in a canyon, I knew it would be loud, I expected it to be loud. But wow. I missed the coyote (I was holding too high on his belly and must have shot right over him since these trail high from my lcr) but he decided to stay gone. My wife was complaining but I'm not sure what about, because I had about 5 minutes of quiet after shooting it.

I'll start with this
1660FPS OUT OF A 357 REVOLVER!!!!
I shot this out of my 6" Ruger gp100. I only put one through the chronograph but it read 1660fps. Incredible. That's 1100 lbs of energy out of a 357 revolver.
I can't remember ever shooting any major manufacturer's ammo every shooting the advertised speed. Always slower no matter the gun or manufacturer. You know that what you are buying is always a bit less powerful than what they say.
Not the case with buffalo bore.
This 180 grain hard cast didn't have specific information for a6" gp100. I was estimating (hoping) for 1600fps. This exceeded my hopes.
I've shot about a dozen rounds of this. It kicks for sure. Truly a magnum load and glad I have a big 357 with full underlug but it's manageable for its use as a hunting cartridge. No signs of excess pressure or issues for the gun.
Once again 1660FPS out of a 357 revolver!
Roger Mattson on 11/05/2021 06:39pm
Wonderful rounds, 686 4", 1,315 fps avg, ES 34, 691 ft-lbs. NO pressure signs, normal extraction,
David Cobb on 05/04/2021 06:41pm
These rounds WILL get your attention at the indoor range. S&W 627/4%u201D sounds more like a .44, and the cylinder flash is amazing!
I use "double ears" indoors, and have experienced some of the 9mm folks abandoning the range when I use these there.
James on 04/24/2021 07:19am
I have quite the hog problem on my middle ga property. I use these in my Browning 92. At around 1800fps from the 92 (lab radar verified) they are pure poison on the pigs! I yet have been able to recover a bullet, doesn%u2019t matter on where they are hit, one hole turns to two!
Great stuff
Michael Garofalo on 02/07/2021 06:53am
Great powerful round! ( 5 shot velocity average ) S&W 586 6" = 1418, Ruger Sp101 4.2" = 1391, Marlin 1894 16.5" = 1840

180G hard cast 357 magnum 5 shots on 3" at 50 yards. with henry big boy magnum 20" barrel with Aimpoint Micro T2.
good combo exceent ammo!
Brian Kloosterman on 08/16/2018 09:24am
I shot .357 magnum heavy buffalo bore ammo from my EAA Windicator snub nosed. My heavy revolver handled this fine. I conducted my own experiments on what I could expect and I was impressed. Bears .stay away.
Mark on 12/29/2015 08:23am
I'm not the best and by far not the worst handgun shooter. This ammunition is the real thing. It don't play! Be ready to adjust your sights. This stuff is moving out when it leaves the barrel so, logically, it won't hit the same spot as the toy stuff. Set it and forget it. These monsters will stack! Gonna order some 125 HPs for home. ME over 800 out of a .357. MEAN!!!!
Thomas Johnston on 05/23/2015 07:14am
Good stuff! You can feel the power of this ammo but the recoil was perfectly manageable with my Ruger GP100 with the special edition 5" barrel. In fact, the recoil was not much harder than some fairly hot range ammo that I have. That ammo has a lighter bullet and a faster MV but the bullet isn't intended for the serious work this Buffalo Bore ammo is designed for. My wife may carry my GP100 loaded with this ammo when we are in grizzly country in the coming weeks. I'll be carrying my Ruger Vaquero (old) loaded with Buffalo Bore ammo. If you are interested in that ammo, see my other review. Whoa baby!
Mike Pace on 11/24/2014 01:08pm
As I like to hike the mountains of Western North Carolina , and it is not uncommon to run into wild hogs and the random black bear , although it is the two-legged varmints that worry me the most . I purchased the heavy 180 grain load and I will tell you they do inspire confidence . Also , they are quite accurate , shooting under two inches at 25 yards out of my Ruger GP 100 . This is a great product !
Frank DeYoung on 11/08/2014 07:45am
fyi; I had to kill a couple of beef for a friend they were about 500lbs on the shy side. I shot one with BB 180 hard cast out of a 4" 686 at 10 yards face on. I wanted to find the bullet. We after just shy of 36" of penetration. You read it right 36". Wow BB what a great product. I will carry it into bear country. No matter what you still have to hit the spot no matter what you carry.
Thank you
George on 10/26/2014 04:21pm
Wow! Put some good dents on an AR 500 target using 3" SP101 & 6" GP100. Recoil was not as bad as I had expected. THIS is the penultimate 357 woods ammo.
Andrew on 09/19/2014 07:27pm
I shot 5 total rounds of the 180 grain lead cast loads through a Ruger LCR at AR 500 steel at approximately 10, 20, & 40 yards. It was not fun by ANY stretch of the imagination, but it is my chosen combination for a pocket pistol while backpacking in Arkansas. After each shot, I inspected each round for crimp jump. Somewhere between rounds 2 & 3, I discovered 2 rounds had jumped crimp approximately 1 mm as compared to unused rounds from the box. This caused no issues with cylinder rotation, and all 5 rounds functioned flawlessly. At 40 yards, rounds impacted about 1 foot above point of aim. I am confident with carrying my chosen combination and hope to never need it.

My wife carries a Colt Lawman Mk III when we're camping and hiking. I bought a box of these Heavy 180 gr. Buffalo Bore rounds to give her the most power in that revolver. I've been able to load up some potent .357 rounds myself, but nothing like these. Out of curiousity we chronographed one of these heavy BB rounds. Out of her 4" J-Frame Colt this round gave us a solid 1,350 fps. I was expecting 1,300 so I was delighted. Recoil is snappy, but not punishing. Because of the cost we only fired 4 rounds, but accuracy seemed pretty good. The Lawman Mk III isn't a very big gun, but this 180 gr. Heavy 357 Magnum load is still very manageable. I'd like to see this load with a semi-wadcutter, but that's just my preference. This is a fantastic load!
Jennifer Thomas on 07/12/2013 11:12am
A real eye opener. Living on the edge of the National Forest I can't think of a better round for my Security Six. With a 6" barrel I have accuracy and punch. This may or may not stop a bear, I hope never to find out, but I feel much better in the woods with my Buffalo Bore at my side. My thanks to Tim
Don Bedford on 06/22/2013 08:55am
I compared a penetration test on this ammo and was very impressed. I stacked and fastened 10 2x4 studs together which totaled about 15 inches. From about 1 foot I fired different ammo from two guns, Ruger SP101 .357 magnum 2-1/4 barrel and Model 1911 Colt .45. The ammo I tested was standard FMJ 125 grain .357 magnum, 230 grain ball ammo for my .45, and the Buffalo Bore 180 grain heavy .357 magnum loads. The standard 357 and 45 ammo penetrated three 2x4’s which is 4.5 inches. The Buffalo Bore ammo penetrated about half way into the seventh 2x4 which measured 9.5 inches!

I found the Buffalo Bore 158 grain 357 Magnum load to be a very effective, accurate, and powerful load for the 357 Magnum revolver. Despite "hear-say" that the 357 magnum is not powerful enough for deer sized game, with the Buffalo Bore offereings, you'll find that arguable statement ot be a myth at best.
It almost goes without saying, but these 357 Magnum offerings from Buffalo Bore are also fantastic defense rounds, and more than capable of one-shot/stop the threat immediately!
Payton Varnadore on 05/03/2011 02:42pm
As with the .380 I've ordered, this 180 grain ammo is great. Very accurate in my Security Six and with power to spare. I was hoping to carry it in my SP101 as a back up against hogs when turkey or quail hunting, but my accuracy there was not great. Possible the 2.25" barrel just couldn't stabilize this hot round as it seemed to keyhole a bit? Still great ammo, so I'll use it in the woods in my Security Six.
Mark DuBose on 02/18/2011 01:08pm
I bought a box of this ammo for short range whitetail deer hunting for my Ruger 4" GP100. When I first shot this round I was expecting recoil to be very very stout. I was pleasantly surprised when I found out it really felt no different than regular 158 grain .357 loads. I can think of no better loading for woods carry and short range critter protection for the lower 48 states.
Brian on 10/31/2010 06:59pm
Very impressed with the 180 in my 6" GP100. The most accurate .357 ammo I have ever shot. Can't wait to use it this fall.
Chris S. on 09/20/2010 02:56pm
180 gr .357 load in my 6" bbl S
Joe R. on 04/16/2010 06:21pm
This was the forth Buffalo Bore round I tested. The other three, 270 Grain 44 mag., 158 grain heavy 357 mag, 158 grain short-barrel 357 are all best in their class. The 180 grain heavy 357 is more of the same. I don't recommend carrying a 357 in bear country, but the ballistics from this guy are enough to give you a fighting chance. Out of a 6" barrel your pushing 800 Ft. Lbs. This is fabulous. Out of my 3" SmIth, this round pushes 1400 FPS. The old timers say that for protection from bear you need a 200 grain slug traveling at least 900 FPS. The old 45 colt with 260 grains at 960 FPS was good enough to get the job done. This round is even better.
Randy Branesky on 12/28/2009 08:33am
Thanks for a great product. This past weekend I bagged a 110 pound doe and a 200 pound hog with my New Model Blackhawk using your 180 grain heavy 357 magnum ammo. Neither animal took another step. I was a little concerned after reading many peoples opinion that a 357 magnum is not powerful enough for deer and hogs. Not any longer. I will not hesitate to use my 357 with your ammo in the future. Thanks
Bob Schultz on 04/01/2009 02:51pm
Hello Buffalo Bore-
I wanted to know if I could have a tracking number for this order.....
Also, I wanted to thank you for the great ammo. My friend and I just came back from a hog hunt were I bagged a 300 lb sow with the 180 gr. Heavy 357 Magnum Buffalo Bore round. My friend Ralph, bagged a 425 lb boar using the Buffalo Bore 405 gr. 45/70 Magnum ammo. In both cases, the ammo worked perfectly. I only wish that you had the heavy 30-30 round ready.
Again, thank you and keep up the good work
Bob
