The Magtech Sport .357 Magnum 125-grain Full Metal Jacket Flat Point (FMJ-FP) Brass 50-round box is a full-power centerfire cartridge engineered specifically for high-volume target shooting, marksmanship training, and range practice in .357 Magnum revolvers and lever-action carbines. A primary friction point during high-volume range training is clean paper target scoring and projectile safety in tubular magazines, where pointed bullet tips pose a primer-ignition risk under recoil. Magtech completely resolves these operational challenges by utilizing a precision-formed 125-grain FMJ Flat Point projectile, ensuring safe tip-to-primer contact in stacked tubular magazines while punching crisp, easily visible holes in paper targets for fast shot tracking.
The technical advantage focuses on pairing an aerodynamic flat-nose geometry with true magnum pressure curves to deliver authentic recoil impulse and predictable trajectories. Launching its 125-grain FMJ-FP payload at a high-velocity muzzle speed of 1,405 FPS, this load replicates the high-energy flight dynamics of full-power defensive ammunition without excessive barrel wear. Mechanically, the full copper jacket encapsulates the swaged lead core to prevent cylinder gap leading and bore fouling, while the wide flat nose glides up lever-action feed ramps without catching or binding during fast cycling.
Slinging its 125-grain flat-point bullet at 1,405 FPS, this classic .357 Magnum load is optimized for effortless mechanical function in double-action wheelguns, single-action revolvers, and lever-action rifles. Assembled in premium reloadable virgin brass cases fitted with sensitive non-corrosive Boxer primers and clean-burning propellants, it maintains consistent ignition curves and tight internal pressure tolerances. The precision-drawn brass hulls expand smoothly to seal the chamber under peak magnum pressures, then spring back to allow non-binding, effortless ejector rod extraction during rapid reloads.
Key Benefits
