The 30-06 Springfield is one of the all-time classic cartridges. Adopted as the standard U.S. military cartridge in 1906, the 30-06 served through both world wars, Korea, and several smaller conflicts around the globe. In addition to its military duties, the 30-06 was also an instant success in the hunting fields, and has been a mainstay for hunters since. Topped off with the new GameChanger heavy hunting bullet, with its thicker copper jacket and match accuracy, new life has been given to the time-proven 30-06 as a consistent choice in the field. The Sierra GameChanger hunting bullet is the perfect combination of Sierra’s legendary match accuracy coupled with deadly penetration. Sierra re-engineered their legendary MatchKing bullet into a hollow point design for quick expansion and fitted it with a transparent green tip for ballistic uniformity. Inside, the GameChanger features a unique construction that utilizes a special lead alloy surrounded by a tough copper jacket that delivers excellent penetration and expansion at a variety of ranges.
