Remington UMC ammunition in .357 Magnum (brand part no. R23970) loads a 125-grain semi-jacketed hollow point bullet in a 100-round value pack built for shooters who put serious volume through a revolver or lever gun. Remington builds every UMC handgun round with American-made, first-quality, factory-fresh brass and clean-shooting Kleanbore primers, the same fundamentals that matter whether the round is headed to the range, a carry gun, or a hunting trip. The semi-jacketed hollow point exposes lead at the nose for expansion on impact while the jacketed base holds the bullet together, giving practice ammunition that mirrors defensive and hunting performance. This handgun ammunition is built to be the round you can afford to shoot as much as you need to.
