Heavy 357 Magnum Ammo - 180 gr. Hard Cast LFN-GC (1,400fps/M.E. 783 ft. lbs.) - 20 Round Box

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!!!

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!

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

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!

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.

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.

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.

180 gr .357 load in my 6" bbl S

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.

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

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
