Magtech Range/Training .357 Magnum 158gr Semi-Jacketed Hollow Point ammunition (brand part no. 357B) is built for shooters who put hundreds of rounds downrange without wanting to think twice about the bill. Magtech, a Brazilian manufacturer with decades of experience supplying CBC-owned brands worldwide, loads the 158-grain bullet with a copper jacket over an exposed lead nose for expansion at magnum velocities. The brass case is reloadable and holds up to repeated firing, making this an economical option for high-volume range days. Because it shares the same bullet weight and construction as many defensive loads, it also doubles as practice ammunition for a carry revolver. Shooters who want realistic recoil and expansion behavior at a lower cost per round will find this load a solid match.
