Grizzly Ammo Gc45/70+P10 45-70Gov+P 525Gr Fmj Flat Point 20 Per Box/10 Case

Grizzly Ammo 45-70 Government +P ammunition delivers a heavy 525-grain flat-point projectile in a full metal jacket configuration, purpose-built for hunters and shooters who demand serious stopping power from their lever rifles and single-shots. This is big-bore medicine: the 45-70 +P loading pushes the boundaries of the classic cartridge, giving you additional pressure and velocity compared to standard 45-70 Gov rounds, while the flat-point profile is engineered for controlled penetration and a wider wound channel on large game.

The 525-grain weight means substantial momentum downrange and the kind of retained energy that matters on elk, moose, and heavy-bodied dangerous game. Full metal jacket construction ensures the bullet holds together through bone and heavy muscle, rather than fragmenting on impact. If you're running a modern strong action—a Ruger No. 1, Marlin 1895, or similar—the +P designation means you're getting the extra performance that modern metallurgy makes possible, without sacrificing the reliability of the proven 45-70 platform.

Each box contains 20 rounds, and we stock it in 10-box cases for serious hunters and handloaders who burn through ammo on the range or in the field. Grizzly Ammo is known for consistent quality and attention to detail—this isn't the cheapest round on the shelf, but it's built for hunters who won't compromise when accuracy, consistency, and terminal performance are on the line.
