The Remington Core-Lokt 300 Win Mag 150 Grain PSP ammunition represents over seven decades of proven big-game performance. This 20-round box delivers the controlled expansion and weight retention that have made Core-Lokt the go-to choice for hunters across North America and beyond. Whether you're after elk, moose, or distant deer, the 150-grain pointed soft point combines velocity and energy with bullet construction designed to perform when it counts.

The 300 Winchester Magnum is a workhouse cartridge for long-range hunting, and Remington's Core-Lokt load maximizes its capability. The tapered copper jacket is mechanically locked to a solid lead core—a design that has proven itself in the field generation after generation. This engineering delivers consistent expansion and dependable weight retention on game, translating to reliable performance from the range to the backfield.

Core-Lokt ammunition fills a practical middle ground: respected heritage, time-tested bullet design, and sensible value. If you're running a standard 300 Win Mag rifle and want ammunition you can trust without overthinking it, this load gives you the ballistic foundation and terminal performance that established the Core-Lokt name.
