45 Auto rim ammunition is an extremely unique cartridge with a very interesting history. The .45 Auto Rim is a rimmed cartridge specifically designed to be fired in revolvers originally chambered for the .45 ACP cartridge.

The round is very similar to the massively popular 45 ACP cartridge. The 45 Auto Rim was created for a weapon created to meet wartime demands.

The 45 auto rim was entirely lead, which was softer, and aided in resisting wear in the shallow rifling of M1917 revolvers.
