Buffalo Bore 45 Colt +P ammo delivers 300 grains of jacketed flat-nose projectile at 1200 feet per second and 959 foot-pounds of muzzle energy — performance that transforms the .45 Colt into a viable hunting cartridge for deer, black bear, and feral hogs at woods distances. This is 45 Colt +P ammunition loaded to modern SAAMI specifications, intended exclusively for Ruger Blackhawk, Freedom Arms, and other revolvers rated for +P pressures. Do not chamber this load in older Colt Single Action Army, replica revolvers, or rifles not explicitly marked +P-compatible — pressure can exceed the structural limits of vintage actions.
Performance at a Glance
The 300-grain jacketed flat-nose bullet expands the effective range of the 45 Colt platform beyond traditional cowboy loads, while the flat nose punches a full-diameter wound channel through hide, muscle, and bone. Buffalo Bore uses flash-suppressed powder to preserve night vision during low-light hunts. Brass cases are boxer-primed and reloadable, allowing you to tailor loads to your specific revolver once fired brass accumulates.

- Treat every firearm as if it is loaded; keep your finger off the trigger until your sights are on target and you have made the decision to fire; never point the muzzle at anything you are not willing to destroy; be certain of your target and what lies beyond it.
- Verify your revolver is rated for +P pressures before chambering this ammunition — consult your owner’s manual or contact the manufacturer if markings are unclear.
