Sierra has offered a new bullet weight for the time proven 45/70 Government. We developed this bullet to provide a heavier projectile for even larger heavier game with a cartridge that has lived out such a colorful history from blackpowder to the latest powder developments, the 45/70 Gov’t has not only survived, but excelled. We are proud to offer a much desired bullet weight to help enhance penetration and expansion on medium and larger game animals. This offering produces a B.C. of .152 (G1) and sports a sectional density of .272 for deep penetration results.
It may be used in rifles or handguns with a .458 inch bore, but it must not be used in handguns with .451 or .454 inch bore size.
