Product Overview: 300 wsm Winchester brass

The .300 Winchester Short Magnum is a 7.62mm short action magnum cartridge with considerable effect. It is very similar to the regular .300 Winchester Magnum in terms of ballistics but takes advantage of the short action design which allows more powder to sit closer to the flash hole. When the primer ignites, it allows a more uniform burn which in turn translates into more efficient use of energy. A 300wsm brass can therefore achieve the same ballistics with less powder.

Winchester Reloading Brass(300 win short mag brass) is manufactured to extremely tight tolerances to ensure smooth feeding and positive chambering. Consistent case-to-case weight and capacity deliver outstanding accuracy. Winchester’s high-quality, durable brass can be reloaded several times. New, unprimed brass. This is not loaded ammunition.
