Sierra 300 Winchester Gamechanger 180 Grain Tipped Game King

Introduced in 1963, the new 300 Winchester Magnum used the same case length as the rest of the Winchester Magnum family, although the shoulder was moved forward to allow greater powder capacity.This increased capacity made it one of the most potent commercial 30 caliber magnum capable of use in a standard (30-06 length) action. The 300 Winchester Magnum is primarily a hunting cartridge, buthas enjoyed considerable success as a 1000 yd target round. As a big game cartridge, it is ample forany North American big game species. With its flat trajectory, it is well suited to the long-range
shooting conditions frequently encountered in western big game hunting.
