NEW BUFFALO BORE APPAREL
BUFFALO-BARNES LEAD-FREE HEAVY 357 Mag
140 gr. Barnes XPB @ 1550 fps
20 Round Box
PRESS RELEASE FOR BUFFALO-BARNES HEAVY 357 MAG 140 gr. BARNES XPB
For those wanting/needing a lead-free, HEAVY 357 Magnum load, generating full power plus, here it is.
Below are real world velocities taken from my personal stock guns. The industry established use of long laboratory test barrels that give false high-velocity readings is essentially misleading to the public who won’t be firing the ammo from a laboratory test barrel in the real world, where it matters.
➤ 1947 fps—Marlin mod 1894, 18-inch barrel
➤ 1518 fps—S&W mod 27, 5-inch barrel
➤ 1519 fps—S&W MT Gun, 4-inch barrel
➤ 1436 fps—S&W mod 66, 3-inch barrel
➤ 1385 fps—S&W mod 66, 2.5-inch barrel
You’ll notice the newer S&W 4 inch Mt. Gun, gave higher velocities than the older 5-inch mod 27 S&W. This is because of different internal barrel dynamics and chamber dimensions of the newer gun. In general, the newer S&W revolvers are made to tighter tolerances than those of 30+ years ago.
Due to the long-for-weight all copper bullet, the 357 does not have the case capacity to use a bulky flash retarded powder and thus there is a noticeable muzzle flash with this load in all the test revolvers; however, the rifle shows no flash at all due to its longer barrel.
This load is the typical barn-burning, turbocharged, Buffalo Bore type HEAVY 357 Mag. load and as such, should only be used in revolvers made of all steel. It should not be fired in a lightweight, alloy framed or cylindered revolver. Feel free to use it in ANY/ALL 357 mag. chambered rifles and all steel revolvers/handguns.
