Buffalo Bore Ammunition 45 Auto Rim (Not ACP) 225 Grain Hard Cast Lead Wadcutter 500 rounds



Buffalo Bore loads their ammunition up to maximum SAAMI specifications, which delivers devastating performance on a wide range of game. Please note that this ammunition is safe to use in older prewar revolvers in proper working condition. This ammunition is new production, non-corrosive, in boxer primed, reloadable brass cases.

Owner of Buffalo Bore Tim Sundles on Heavy 45 Auto Rim Ammunition:

This 225gr. full profile wad cutter, 45 auto rim, is the most deadly standard pressure load ever devised for the 45 auto rim cartridge. It utilizes the same bullet as our 45 colt ANTI-PERSONNEL ammunition (Item 3I) and because of popular request to have that bullet loaded into 45 auto rim ammo, here it is.

This bullet will penetrate around 28 inches and makes a permanent crush cavity because of its wad cutter profile. This load is the power/pressure level equivalent of 45 acp+P ammo and is safe to use in all modern 45 acp revolvers, including any/all (even pre war) 1917 model revolvers in normal operating condition.

Flash suppressed powders are used in this ammo so the shooter will not be blinded by his own gunfire and gives a tactical advantage.

The 225gr. wad cutter bullet is hard cast (not lead) and is properly lubed and will not substantially lead foul your barrel even after extensive shooting sessions, nor will the bullet fragment, smear or mushroom on impact with flesh and bone, thus insuring very straight and deep penetration with a consistent crush cavity throughout its path.

Note the velocities we obtained from stock factory revolvers:

  • 983 fps — S&W Mt. Gun, 4 inch barrel
  • 909 fps — S&W Mod. 325PD, 2.5 inch barrel
