Underwood Ammo ammunition in .45-70 Government (part no. 750) loads a 430-grain hard cast flat nose gas-check bullet at a listed 1,550 feet per second, built for hunters and backcountry shooters who need maximum straight-line penetration on the biggest, most dangerous game. The hard cast lead alloy resists deforming on impact, so the bullet drives a full-diameter wound channel through heavy muscle and bone rather than expanding and shedding energy early. A gas check on the base protects the soft lead from high-pressure gas cutting, preserving accuracy at full-power .45-70 velocity. For shooters who carry .45-70 specifically for deep-penetrating stopping power, this rifle ammunition is built for that exact purpose.

Frequently Asked Questions

Why choose a hard cast bullet instead of a jacketed soft point? Hard cast lead resists deforming on impact, driving a full-diameter wound channel through heavy muscle and bone rather than expanding and losing energy early, useful against the biggest, most dangerous game.

What does the gas check do on this bullet? It is a small metal cup on the base that protects the soft lead from high-pressure powder gas cutting into it, preserving accuracy at full-power velocity.
