If you're running a .480 Ruger and want ammunition that shows up when it matters, Buffalo Bore's Heavy load is the real deal. This is a full-power offering that launches a 370-grain hard cast lead flat nose bullet at 1300 fps with 1388 ft-lbs of muzzle energy. That combination of velocity and weight creates the kind of penetration that works on tough game.
Buffalo Bore makes their Heavy load in two versions. This particular one (13A20) is their full-power offering, designed to push the round to its maximum while staying within safe pressures. If you've noticed similar 480 Ruger ammo that runs at 1000 fps, that's their Low Recoil variant. This Heavy load doesn't hold back. The 370-grain bullet is a London Bridge Trading design with a flat nose profile. That flat nose doesn't expand on impact, which is the whole point here. It's built to penetrate straight and deep, creating a large wound channel through heavy bone and muscle. The .475 diameter bullet naturally makes a bigger hole than traditional .45 caliber cartridges, and at 1300 fps, you get dramatic impact and energy transfer on game animals.
The .480 Ruger itself sits in an interesting spot in the big-bore revolver world. It delivers power that exceeds the .44 Magnum while keeping recoil manageable compared to the .454 Casull or .475 Linebaugh. Buffalo Bore's Heavy load maximizes that advantage. Medium to large game like deer, hogs, and black bear within typical hunting distances are where this ammunition proves its worth. The hard cast construction handles bone impacts without deformation, and the penetration is substantial even after encountering heavy material. This is ammunition built around field performance, not expansion, which is exactly what works when you need deep, reliable penetration through thick bone and dense muscle.
The Heavy load (13A20) runs at full power and pushes 1300 fps with 1388 ft-lbs of energy. Buffalo Bore's Low Recoil variant (13B) uses the same 370-grain bullet but runs at 1000 fps with roughly half the recoil and blast. Both use hard cast flat nose bullets that don't expand, but the Heavy load delivers more impact energy and penetration potential for larger game or longer distances.
No. Buffalo Bore's hard cast flat nose bullets are designed not to expand on impact. The flat nose creates a large wound channel through sheer frontal area and penetration rather than expansion. This is intentional for deep, reliable performance on tough game animals. The penetration works even when the bullet hits heavy bone.
This heavy load works well on medium to large game like deer, hogs, and black bear at typical field hunting distances. The 370-grain bullet's combination of weight and velocity delivers the kind of deep penetration and energy transfer that handles these game animals effectively. Shot placement remains important, but this ammunition gives you the power to anchor game reliably.
The .480 Ruger is chambered primarily in the Ruger Super Redhawk revolver, which is available with either 7.5-inch or 9.5-inch barrels. Some custom single-action revolvers also chamber this cartridge. Always verify your specific firearm is chambered for .480 Ruger before purchasing ammunition.
