HSM Bear Ammunition 454 Casull 325 Grain Lead Wide Flat Nose Gas Check Box of 50

HSM Bear Ammunition in 454 Casull loads serious stopping power for hunters and sportsmen working in dangerous game country or handgun hunting scenarios where penetration is non-negotiable. This particular load pairs 325-grain lead wide flat-nose bullets with HSM's proven handloading standards. Each round is built with hard-cast projectiles featuring a gas check—a brass cup seated at the base to prevent bullet deformation in the chamber and maintain consistent performance downrange.

The 454 Casull is already known for its raw power, and HSM's "Bear Load" formulation is engineered to deliver the deep, straight-line penetration required in thick-skinned game or situations where expansion takes a backseat to relentless pass-through performance. The wide flat nose delivers a larger frontal area than a traditional round nose, while the hard-cast construction resists deformation under the pressures of a big-bore magnum. Whether you're running this through a Ruger Super Redhawk, a Freedom Arms, or another quality 454 platform, these rounds are built to the same quality standards HSM applies across its lineup.

HSM has been manufacturing ammunition since 1971, and their centerfire handgun rounds are respected by serious shooters for consistent velocity and reliable ballistics. Each box contains 50 rounds, giving you plenty of opportunity to pattern your load and have a working supply on hand.

Frequently Asked Questions

What firearms does HSM 454 Casull ammunition work in?

454 Casull ammunition is designed for revolvers chambered in 454 Casull. Common platforms include the Ruger Super Redhawk, Freedom Arms, and other quality revolvers built for this magnum cartridge. Always verify that your specific firearm is properly chambered before loading and firing.

Why does this load use hard-cast bullets with a gas check?

Hard-cast lead with a gas check is engineered to resist deformation under the extreme pressure and velocity of a 454 Casull magnum. The gas check (a brass cup at the bullet base) prevents the bullet from collapsing in the chamber and ensures consistent penetration. This design is ideal when you need straight-line, deep performance—especially for hunting or defense scenarios where expansion is less important than complete pass-through.

What is muzzle velocity for this ammunition?

HSM loads this 325-grain round to 1330 feet per second from a 9.375-inch barrel, generating 1277 foot-pounds of muzzle energy. Actual velocity may vary depending on your barrel length, firearm condition, and environmental factors.

How many rounds are in a box?

Each box contains 50 rounds of finished ammunition, ready to shoot.
