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.Specifications:Manufacturer: SierraModel Number: A466906Ammo Bullet Type: Tipped GameKingAmmo Casing Type: BrassAmmo Bullet Weight: 165 grainAmmo Round Count: 20/BoxCaliber Multi: .30-06 SpringfieldMuzzle Energy: 2997 lb/ftMuzzle Velocity: 3000 fpsApplication: Medium, Large GameSeries/Collection: GameChangerBallistic Coefficient: 0.517
