Overview
Built for hunters who need a hard-hitting .45-70 Government load, this +P cartridge is intended for demanding big-game and bear-country use. It is loaded to higher-than-usual pressure for enhanced velocity and a flatter trajectory, so it should only be used in firearms rated for +P ammunition and verified in the owner’s manual. Grizzly Cartridge Co. produces it in small batches with close quality control, and the 300-grain JHP load is offered in a 20-round box. Recoil is a real consideration with this ammunition, but it is aimed at hunters who want a serious option for heavy game.

- The increased pressure comes with heavier recoil, which may be a meaningful trade-off for some hunters.
- It is a specialized .45-70 Gov’t load, so it is best suited to compatible rifles rather than general-purpose use.
- The 20-round package is relatively limited if you need a larger supply for extended practice or multiple outings.
