Owner of Buffalo Bore Tim Sundles on Buffalo Bore Heavy 357 Magnum Ammunition:

For those wanting the deep-for-weight penetration of the all copper (lead free) Barnes XPB 125gr. bullet in a ?tactical? loading, here it is. We use low flash powder so the shooter will not be blinded by his own gunfire, as nearly all self defense shootings in America occur in low light when the criminal element is out and about.

Our tactical 357 mag. ammo generates less felt recoil and blast (flash and noise) than our Heavy 357 mag. loads and as such is a better choice for those carrying light weight short barreled revolvers. This is still a full powered 357 mag. load, but allows for faster follow-up shots and greater shooting comfort.

Below are real world velocities taken from my personal real world stock guns. The established use of long laboratory test barrels that give false high velocity readings are essentially misleading to the public who won’t be firing ammo from laboratory test barrels.

1642 fps – Marlin 1894, 18 inch barrel1333 fps – S&W mod. 27, 5 inch barrel1383 fps – S&W Mt. Gun, 4 inch barrel1295 fps – S&W mod 66, 3 inch barrel1235 fps – S&W mod 66, 2.5 inch barrel

Yes the more modern 4-inch S&W Mt. gun did shoot faster velocities than the older 5-inch model 27 and this is due to different internal barrel dynamics of the newer gun.

This ammunition is safe for use in ANY/ALL 357 magnum firearms.
