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.

We are introducing a .4515” diameter bullet to provide an outstanding bullet weight that will be ideal in the prevalent .450 Bushmaster. Excellent feeding capability was of utmost importance along with the deepest penetration and expansion qualities combined. The flatnose allows the projectile to deliver tremendous energy transfer on game such as boar and bear. Yet deliver reliable expansion even on smaller game like coyotes. This 450 Bushmaster will be an ultimate bullet for deer as well. All of this performance and sporting a G1 B.C. of .164 and sectional density of .182 will prove this to be the excellent fodder for the mighty .450.
