The Grizzly Ammo GC45/70+P7 brings serious stopping power to your 45-70 rifle with a 420-grain wide long nose gas-check bullet. This is a +P specification load, which means it's designed specifically for modern rifles with stronger actions—not for original trapdoor-style firearms. The wide long nose gas-check design helps deliver consistent performance downrange, and at 2000 fps with 3730 ft-lbs of muzzle energy, you're getting a load built for effective hunting where penetration and retained velocity matter.
This particular bullet design has been a go-to choice for hunters who need heavier projectiles that hold together under demanding conditions. The gas-check base helps reduce fouling in your barrel while promoting consistent velocity, and the wide long nose profile delivers deep penetration on big game. With this much bullet weight moving at these velocities, you've got a load that delivers real stopping power at typical hunting ranges.
Because this is a +P load, it requires a rifle with the action strength to handle the increased pressure. Modern lever-action rifles like the Marlin 1895, Henry Steel Lever, and similar modern designs are right in the wheelhouse. Always verify your rifle's rating before using any +P ammunition. You'll get solid accuracy and reliable expansion from this factory ammunition, which has been quality-tested throughout the manufacturing process.
Each box contains 20 rounds, and the 10-box case packaging makes it convenient for serious hunters who stock up. Whether you're hunting in thick timber or preparing for extended range sessions, this is a load built for rifles and applications where you need maximum bullet mass working in your favor.
No, this is a +P load and is specifically designed for modern rifles with stronger actions. Original trapdoor rifles and their replicas cannot safely handle +P pressure levels. Always verify your rifle's specifications and use ammunition rated for your specific firearm's pressure capabilities.
The gas-check base reduces barrel fouling and helps maintain consistent velocities shot to shot. The wide long nose profile delivers excellent penetration on heavy game while resisting deformation in tough conditions. This combination makes it reliable for hunting applications where deep penetration is important.
The 45-70 platform performs best within 100 to 200 yards, where this load delivers its full terminal performance. At 2000 fps with a 420-grain bullet, you'll have excellent energy retention across this range. Beyond 200 yards, bullet drop increases significantly, so closer shots are where this load truly shines.
Yes, this +P load is designed for modern lever-action rifles like the Marlin 1895 and similar contemporary designs. These rifles have the action strength necessary to safely handle the increased pressure. Verify your specific rifle's manual to confirm it's rated for +P ammunition before use.
