Starline Brass .45 Auto Rim Brass 100 Pack

The .45 Auto Rim was developed shortly after the First World War to allow revolvers chambered for the .45 Auto to be fired without the use of moon clips. By incorporating an extra-thick rim, the cartridge headspaces correctly in revolvers originally designed for the rimless .45 ACP, providing a simple and reliable solution for shooters who prefer conventional extraction and loading.

Built to the same high standards as Starline's renowned .45 Colt brass, the .45 Auto Rim is an excellent choice for target shooting, recreational shooting, and traditional revolver use. It remains particularly popular with owners of classic Smith & Wesson and Colt revolvers originally chambered for the .45 ACP using moon clips.

At Hamilton’s Armoury, we back Starline Brass because it’s built with the same mindset we apply to everything we do — no shortcuts. With over 30 years of dedication to quality, Starline continues to produce premium brass for those who take their shooting seriously.

Note: Due to its extra-thick rim, .45 Auto Rim brass is designed specifically for revolvers chambered for the .45 Auto Rim or .45 ACP with moon clips. It is not suitable for use in single-action revolvers chambered for .45 Auto (such as the Ruger Blackhawk with a .45 Auto cylinder) or in dual-cylinder revolvers designed for both .45 Colt and .45 Auto in the same cylinder (such as the Ruger Redhawk or Smith & Wesson Governor).
