The Magtech 357B delivers consistent performance for .357 Magnum training and range sessions with its 158-grain semi-jacketed hollow point design. This Brazilian-manufactured ammunition provides reliable feeding and ejection across revolvers and lever-action rifles chambered in .357 Magnum.

What Makes This Different

Magtech's semi-jacketed hollow point construction combines controlled expansion with deep penetration, making it suitable for both training applications and situations requiring stopping power. The 158-grain bullet weight matches traditional .357 Magnum loadings, providing authentic recoil characteristics for training purposes. Quality control standards ensure consistent velocities and reliable ignition across temperature ranges.
