300 WSM – 150 gr PP – Winchester Super-X (X300WSM1) – 200 Rounds

Winchester created the 300 WSM, and Super-X Power-Point is the company’s long-standing hunting load. This listing is Winchester Super-X 300 WSM 150 grain Power-Point ammo, MPN X300WSM1, sold as a 200 round bulk case for deer and pronghorn hunters who want speed and a flat trajectory.

The Power-Point bullet uses a contoured jacket and exposed lead tip for fast, reliable expansion and dependable weight retention. Winchester rates this load at 3,270 fps with 3,561 ft-lbs of muzzle energy. That flat trajectory simplifies holdover at longer ranges in open country.

The 300 WSM (Winchester Short Magnum) fits short action bolt rifles such as the Winchester Model 70, Browning X-Bolt and A-Bolt, and other rifles chambered for it. It delivers near 300 Win Mag performance from a shorter, fatter case. A common question is whether 300 WSM ammo can be fired in a 300 Win Mag rifle, and the answer is no: the cases are completely different, so only use this ammo in a rifle stamped 300 WSM. Its short, wide case burns powder efficiently, so a 300 WSM rifle can be lighter and handier than a full-length magnum while still reaching elk and big game at long range, with more recoil than a 308 or 30-06. A 200 round case means one consistent lot for sighting in and many seasons of hunting.

Winchester Super-X X300WSM1 is new production ammunition, not reloads, made in the USA. Each cartridge uses a brass case with a boxer primer and is non-corrosive, and the boxer primed brass is reloadable for handloaders. Buying by the case also keeps you on one production lot, so point of impact and velocity stay consistent from box to box. This case comes in factory packaging as 10 boxes of 20 rounds for a total of 200 rounds of 300 WSM 150 grain Power-Point.
