IMPORTANT INFORMATION ABOUT THE HEADSTAMP ON THIS BRASS: Due to limited supplies of brass, Buffalo Bore has begun loading +P and +P+ ammunition in brass that may not be indicated as such on the headstamp. Example: 9mm Luger +P+ ammunition may be designated as 9mm Luger +P or simply 9mm Luger on the headstamp.
Buffalo Bore loads their ammunition up to maximum SAAMI specifications, which delivers devastating performance on a wide range of game. These Heavy .45 Colt +P loads are safe in all LARGE FRAME Ruger revolvers.(includes Blackhawk, Super Blackhawk, all pre-2005 Vaquero, Bisley, Redhawk) These Heavy .45 Colt +P loads are NOT intended for the New Model Vaquero (small frame). These loads are also safe in all modern Model 1892 leverguns as well as all Winchester & Marlin 1894’s Please note that this ammunition is not intended for older guns. It is made for modern firearms only, as some of the ammunition could damage older and weaker firearms. This ammunition is new production, non-corrosive, in boxer primed, reloadable brass cases.

Owner of Buffalo Bore Tim Sundles on 45 Colt +P Ammunition:

FOR USE ONLY IN GUNS CONSTRUCTED TO WITHSTAND +P 45 COLT AMMUNITION

As usual we test fire our published velocities from real world over-the-counter firearms, so the customer will have an idea what this ammunition is doing in the real world, where it matters and not in a laboratory. We feel that publishing velocities fired from very long laboratory test barrels, gives false high velocity readings and is misleading to the customer. See our velocities below:

1533 fps – Freedom Arms Mod. 97 5 1/4 inch barrel1505 fps – Ruger pre 2006 large frame Vaquero 5 1/2 inch barrel1855 fps – Marlin Mod. 1894 Cowboy 20 inch barrel

This, long-for-weight, Barnes X style bullet will penetrate deeply for such a light weight bullet and therefore this load is suitable for big game from whitetail deer through elk.

Barnes placed the crimp groove in a location that affords a short cartridge OAL; therefore the loaded cartridge will fit into the short cylinder of the FA mod. 97. The OAL for this cartridge is 1.572 inch. Which means you can chamber it in revolvers that are too weak to fire +P loads. So, use this ammo ONLY in ALL LARGE FRAME RUGERS, (i.e. Black Hawks, all Red Hawk iterations chambered in 454 Casull and 45 Colt, and pre 2006 Vaqueros) Colt Anaconda, all FA revolvers chambered in 454 Casull and 45 Colt and Dan Wesson revolvers, Winchester and Marlin mod. 1894, all falling block actions made of modern steel, TC Encore and the Handi Rifle.
