Grizzly Ammo Gc45/70+P7 45-70Gov+P 420Gr Wide Long Nose Gas Check 20 Perbox

The Grizzly Ammo GC45/70+P7 is a premium handloaded 45-70 Government +P round designed for hunters and shooters who demand precision and power from their lever-action rifles and single-shot rifles. Each box contains 20 rounds loaded with a 420-grain wide long nose bullet featuring a gas check—a design that maximizes bullet stability and consistency downrange while protecting the bullet base during firing. This is ammunition built for serious hunters pursuing big game where a combination of accuracy and stopping power matters.

The 45-70 Government +P cartridge sits at the upper end of the 45-70 spectrum, delivering the kind of velocity and energy that larger-frame rifles are built to handle. The 420-grain projectile is a substantial, no-nonsense bullet choice—the kind of weight that sustains energy over distance and maintains velocity in less-than-ideal conditions. Gas check ammunition reduces leading in the barrel and improves shot-to-shot consistency, especially important when you're reloading or using handloaded ammunition where uniformity directly affects your groups and confidence in the field.

Grizzly Ammo specializes in quality handloaded centerfire rifle ammunition, and this 45-70+P load reflects that commitment to shooters who understand their rifle's capabilities and expect their ammo to match. Whether you're hunting elk, moose, or working with a specialty rifle that thrives on heavier loads, this round deserves consideration. Store in a cool, dry place and handle according to all firearm and ammunition safety guidelines.

Specifications

Frequently Asked Questions

What rifles are compatible with 45-70 Government +P ammunition?

The 45-70 Government +P is designed for rifles specifically rated for +P pressures. This includes modern lever-action rifles and single-shot rifles built to handle higher-pressure loadings. Always verify your rifle's manual and pressure rating before using +P ammunition; standard 45-70 rifles are not designed for +P loads. Never use +P ammunition in a rifle not rated for it.

What is a gas check bullet, and why does it matter?

A gas check is a small copper cup seated on the bullet's base. It reduces leading—copper and lead fouling—in the barrel during firing, which extends barrel life and improves consistency shot to shot. Gas check ammunition is especially valued in handloaded and specialty ammunition for its contribution to accuracy and low-maintenance shooting.

Is this ammunition suitable for hunting, or is it range-only?

The 420-grain 45-70+P load is purpose-built for hunting applications where substantial energy and proven bullet performance are required. The weight and design are consistent with a hunting cartridge, though any ammunition choice depends on your specific rifle, game, and hunting regulations.

How much ammunition is in a box, and what's the case quantity?

Each box contains 20 rounds. The product is available in boxes of 20, with 10 boxes available per case for those purchasing in bulk.
