Grizzly Ammo Gc45/70+P5 45-70Gov+P 405Gr Wide Long Nose Gas Check 20 Perbox

The Grizzly Ammo 45-70 Government +P ammunition delivers serious stopping power for hunters and shooters who demand a heavy-hitting centerfire rifle round. Built for lever-action and single-shot rifles that can handle the +P pressure rating, this 405-grain wide long nose gas check load brings the kind of energy and penetration that defines the 45-70 cartridge's legendary reputation. Whether you're hunting big game in thick country or running precision loads through a suppressed rifle, Grizzly's commitment to consistent, quality ammunition means you can focus on the shot.

The 405-grain bullet weight sits in the sweet spot for hunters seeking bone-breaking energy at hunting distances without excessive recoil—or the logistics headache of factory ammo scarcity. The gas check design protects the bullet base during firing, a smart engineering touch that supports accuracy and pressure consistency across the string. Grizzly Ammo comes from Rintoul, a reloading-focused manufacturer with deep roots in ammunition design. Each box contains 20 rounds, a typical format for centerfire rifle ammunition.

If you shoot 45-70 regularly—whether in a Marlin, Ruger, or single-shot rifle—having dependable ammunition on hand means more time at the range or in the field and less time scrambling for stock. 45-70 +P rounds do require firearms rated for the higher pressure, so verify your rifle's specs before loading.

Frequently Asked Questions

What rifles can shoot this 45-70 +P ammunition?

The +P pressure rating requires a rifle specifically rated for higher pressure loads. Verify your rifle—whether a lever-action Marlin, Ruger, or single-shot—can handle +P ammunition before shooting. Standard 45-70 rifles may not be safe with this load.

What is a gas check on a rifle bullet?

A gas check is a small copper cup attached to the base of the bullet. It protects the bullet material during the high-pressure firing event, helps prevent leading in the barrel, and contributes to more consistent pressure and velocity across your shooting session.

Is this ammunition suitable for hunting?

The 405-grain weight and gas check design make this round well-suited for hunting applications where penetration and energy retention matter. Always follow local hunting regulations and select ammunition appropriate for your game and shooting distance.

Can I reload the cases?

Grizzly Ammo cases are reloadable, a cost-effective advantage for shooters who reload their own 45-70 ammunition. Save the brass after firing and process it according to your reloading equipment and manual.
