If you run a conversion cylinder in your cap-and-ball revolver, this is the brass you need. These genuine Starline .45 Long Colt cartridge cases are ideal for shooters using Howell’s Old West Conversion Cylinders and similar drop-in conversion systems. They provide a dependable, modern cartridge platform while letting you enjoy your classic percussion revolver with metallic cartridges.
 
Starline brass is manufactured in the USA from high-quality cartridge brass and held to precise tolerances for uniform length, consistent wall thickness, and reliable primer pocket fit. That consistency is especially important in conversion cylinders, where smooth chambering and proper case fit are critical to safe and trouble-free operation.
 
These cases pair perfectly with our .452", 228-grain bullets (Item #: MB45CC30), allowing you to assemble period-appropriate, low-pressure .45 Colt loads tailored specifically for converted revolvers.
