Buffalo Bore Ammunition 3G20 Buffalo-Barnes VOR-TX 45 Colt (LC) +P 225Gr Handgun Ammo - 20 Rounds - 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" which means you can chamber it in revolvers that are too weak to fire +P loads. 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.
