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, allowing 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 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.
