Buffalo Bore Ammunition 45 Auto Rim (Not ACP) 200 Grain Jacketed Hollow Point 20RD

If you're running a revolver chambered in .45 Auto Rim—or hand-loading for one—Buffalo Bore's 45 Auto Rim 200 Grain Jacketed Hollow Point rounds are built to deliver. Unlike the more common .45 ACP, .45 Auto Rim was designed specifically for revolvers, using a rimmed case that headspaces on the rim rather than the case mouth. Buffalo Bore has loaded this classic cartridge with a 200-grain jacketed hollow point at standard pressure, giving you a load that's reliable in wheelguns without excessive wear on your action.

Buffalo Bore's reputation rests on ammunition that works in real-world conditions. Their quality control is tight, and their powders and primers are chosen for consistency and reliability. This 200-grain JHP load strikes a balance between velocity and bullet weight, making it suitable for both target work and defensive carry if you're keeping a revolver as a backup gun or primary. The jacketed hollow point is designed to expand reliably on impact, which matters if you ever need to use it.

You get 20 rounds per box, which is the standard loading for .45 Auto Rim ammunition. If you're a revolver enthusiast, a reloader, or someone who's inherited or picked up a vintage .45 revolver and actually wants to shoot it, this is the kind of load that respects the cartridge's original purpose—and the gun it was made for.

Frequently Asked Questions

Will this work in my .45 ACP revolver or gun?

What's the difference between .45 Auto Rim and .45 ACP?

.45 Auto Rim is a revolver cartridge with a rimmed case, originally designed for older swing-out cylinder revolvers and some semi-automatic pistols. .45 ACP is a rimless cartridge for semi-automatic pistols. The rim on Auto Rim allows proper headspacing in revolvers without the need for moon clips.
