Starline Brass - 38-55 Long Win (50pk)

Starline Brass .38-55 Long Winchester Brass 50 Pack

The .38-55 Winchester is one of America's classic sporting and target rifle cartridges, originally developed in the late 1800s for the Ballard rifle before being adopted by Winchester. Celebrated for its exceptional accuracy, mild recoil, and effectiveness on medium game, it remains a favourite among traditional rifle enthusiasts, Black Powder Cartridge Rifle (BPCR) competitors, and Cowboy Action shooters.

This Starline brass is manufactured to the original 2.125" case length, making it suitable for .38-55 rifles with chambers designed to accept the longer case. Featuring a thinner case mouth with an average wall thickness of approximately 0.0072", it accommodates a broader range of bullet diameters and is particularly well suited to rifles with tighter chambers or larger bore dimensions, providing greater flexibility for precision handloading.

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: This is the original 2.125" length .38-55 case. While most rifles chambered for .38-55 will accept this longer case, chamber lengths can vary between manufacturers and production periods. Always confirm your rifle's chamber dimensions before selecting brass.
