Magnus Bullet Co. Allstar/Magnus Cowboy Bullets in .357 Magnum / .38 Special, 125 grain RNFPBB are cast projectiles engineered for shooters who demand consistent performance across a wide velocity range without compromising barrel integrity. Built from a proprietary alloy blend of 91% lead, 4% tin, and 5% antimony, these bullets achieve sufficient hardness to handle velocities approaching 1200 feet per second while resisting leading—a critical concern for high-volume shooters using magnum loadings in revolvers and lever-action carbines.
The 125-grain weight at .357-inch diameter strikes the balance most revolver platforms demand. This mass provides sufficient momentum for reliable expansion and penetration in defensive scenarios while remaining light enough to generate the velocity needed for flat trajectories in hunting applications. The round-nose flat-point design (RNFPBB) minimizes shaving in magazine-fed platforms and presents a reliable bearing surface in cylinder throats. The alloy composition prevents shattering on steel targets—essential for shooters running drills at indoor ranges or steel-plate facilities without risk of dangerous fragmentation.
Operators, law enforcement trainers, and precision handgun competitors rely on cast ammunition for economical high-volume practice that doesn't sacrifice accuracy or reliability. The 500-count package supports extended range sessions, competition prep, and load development without excessive inventory management. Cast bullets from Magnus allow serious shooters to maintain proficiency and work up loads tailored to their specific firearms—whether for duty-carry validation, cowboy-action competition, or magnum hunting loads.
Cast ammunition represents a mature technology with proven track record across defense and sport shooting disciplines. The .357 Magnum / .38 Special cartridge pair remains one of the most versatile defensive calibers in service, and properly loaded cast projectiles deliver the ballistics and reliability professionals expect.
