Winchester built the Super-X line on a foundation of reliability and field performance that's earned respect across generations of hunters. This .300 WSM load pairs the proven Power-Point bullet with solid ballistics to give you the power of a magnum in a short-action platform.
The Power-Point bullet design has been stopping game since the 1960s. Its exposed soft lead tip initiates rapid expansion, while strategically-placed notches around the jacket mouth work to ensure uniform expansion and energy transfer. The result is consistent, controlled expansion that penetrates deep while creating a devastating wound channel. This isn't fancy bullet technology, but it's proven technology that does the job shot after shot.
At 3270 fps muzzle velocity with 3561 ft-lbs of energy, this 150-grain load delivers ballistics nearly identical to the full-size .300 Winchester Magnum, but from a lighter, shorter-action rifle. That means less recoil than you might expect, easier follow-up shots, and a platform that's more maneuverable in the field. The flat trajectory makes accurate shooting past 200 yards straightforward, even for those still getting a feel for the cartridge.
You get 20 rounds per box loaded in reloadable brass cases with non-corrosive primers. The consistent quality control Winchester brings to the Super-X line means minimal velocity variation between shots, translating to tighter groups and predictable performance where it matters. Whether you're hunting whitetail in thick timber or pursuing elk across open country, the Power-Point's controlled expansion works across the distances and hunting situations most people actually encounter.
The 150-grain Power-Point load works well for deer, elk, antelope, and other medium to large North American game. The .300 WSM generates enough energy and velocity to handle most hunting situations, and the controlled expansion of the Power-Point bullet provides reliable performance across typical hunting ranges.
The .300 WSM produces nearly identical ballistic performance to the standard .300 Winchester Magnum but does it from a shorter, lighter rifle action. You get magnum power with less recoil and a more maneuverable platform, though you'll want to verify your specific rifle's performance since individual guns can vary.
Yes. Winchester loads this ammunition in boxer-primed, reloadable brass cases, making it suitable for handloading after firing. The brass casings are what you'd want to save for reloading components.
The 150-grain load is an excellent choice for flat-shooting performance and velocity. Some hunters prefer heavier bullets (165 or 180 grains) for extended-range hunting or larger game, but the 150-grain Power-Point delivers proven performance at typical hunting distances and carries less recoil.
