Starline 45 Colt Brass

Starline 45 Colt bulk brass is engineered for precision, strength, and repeatable performance in a wide range of handgun and rifle platforms. Built with consistent metallurgy, tight manufacturing tolerances, and over 30 years of industry experience, Starline delivers premium-quality brass trusted by seasoned reloaders. Every piece is guaranteed to have flash hole presence and to be within spec for both length and diameter.

Originally developed for black powder use, the .45 Colt has proven to be one of the most versatile revolver cartridges available today. When loaded with smokeless powder, Starline 45 Colt brass can be safely loaded to .44 Magnum pressure levels—provided the firearm is rated for high-pressure loads. This makes it a favorite for cowboy action shooting, big-bore revolver fans, and hunters alike. It’s a caliber known for both historical significance and modern versatility.

Starline’s vertically drawn manufacturing process minimizes wall thickness variation, providing superior case integrity and extended reload life. For reloaders using .452″ or smaller projectiles, some neck sizing may be required depending on bullet choice and chamber dimensions. Whether you’re building light target loads or heavy hunting rounds, Starline 45 Colt bulk brass provides the reliability and durability reloaders expect.
