If you're running a .454 Casull revolver, you know the power is there, but raw pressure doesn't always translate to real-world performance. Buffalo Bore gets this. Their 7B20 300-grain semi-jacketed flat point load backs off from maximum pressure limits specifically to keep things reliable and shootable.
Why does this matter? The .454 Casull pushed to full pressure can cause heavy bullets to jump crimp inside the cylinder, which is exactly what you don't want when you actually need your gun to work. Fired brass sticking in chambers and unreliable ejection become real problems at those upper pressure levels. Buffalo Bore engineered this load to avoid those headaches entirely.
Loaded to 1,650 feet per second, this 300-grain bullet generates 1,813 foot-pounds of muzzle energy from a handgun—that's serious business without being unnecessarily harsh. The semi-jacketed flat point design delivers controlled expansion and deep penetration. You get stopping power that rivals much heavier loads while keeping recoil and felt blast in a more manageable range. This matters if you're shooting enough to stay proficient.
The brass casing is reloadable if you're into that, and the 20 rounds per box means you have enough to get to the range and stay there. Everything about this load prioritizes function over marketing hype. It shoots clean, it shoots consistent, and it doesn't try to do more than the gun can reliably handle. That's the Buffalo Bore approach—practical ammunition for revolvers that demand it.
Pushing the .454 Casull to full pressure with heavy bullets can cause crimp jump, which ties up the cylinder, and fired brass can stick in chambers. By loading this ammunition at moderate pressures (1,650 fps), Buffalo Bore maintains reliability and shootability while keeping the recoil and blast manageable. You still get serious power—1,813 foot-pounds of muzzle energy—without the problems that come with maximum loads.
Yes. The 300-grain semi-jacketed flat point expands reliably and penetrates deep, giving you terminal performance that works on medium to large game. At 1,813 foot-pounds of energy, this load is capable without being unnecessarily excessive. It's a solid choice for those who want proven hunting performance with less punishing recoil than maximum-pressure alternatives.
Yes, the cases are brass and reloadable. Keep in mind that .454 Casull ammunition uses small rifle primers (not standard pistol primers) due to the high pressures involved, and requires careful attention to published data when handloading.
This ammunition is designed for revolvers specifically chambered in .454 Casull, such as the Ruger Super Redhawk, Taurus Raging Hunter, and Freedom Arms models. Do not attempt to use this ammunition in .45 Colt firearms—while .454 Casull revolvers can safely shoot .45 Colt ammunition, the reverse is not true.
