Originating in 1957, the .454 Casull is a high-performance cartridge developed as a lengthened, magnum-level counterpart to the .45 Colt. The case is longer by 0.100 inches compared with the .45 Colt, preventing it from being fired in .45 Colt chambers while allowing .45 Colt to be used safely in .454 Casull chambers. These Starline cases are supplied unprimed and are intended for handloaders assembling cartridges for recreational, hunting, or precision applications.
