Product Overview
Underwood loads this +P version of the Xtreme Hunter to 2275 fps, generating 3736 ft-lbs at the muzzle. That is serious energy for a lever-action cartridge. The 325gr solid copper bullet with machined flutes creates wound channels through fluid dynamics rather than traditional expansion. This load hits hard enough for elk, moose, and dangerous game.
The +P pressure rating requires a modern, strong action. Marlin 1895s, Henry .45-70s, and Ruger No. 1s handle it fine. Stay away from trapdoor actions or older rifles. The extra velocity flattens trajectory and increases terminal effect at longer ranges. Hunters who want maximum performance from their .45-70 without stepping up to a magnum rifle should look at this load.
- 3736 ft-lbs is near magnum rifle performance
- 2275 fps flattens trajectory significantly
- Solid copper retains 100% weight
- Xtreme Hunter flutes create effective wound channels
- Handles elk, moose, and dangerous game
- +P pressure limits use to modern strong actions
- Heavy recoil requires good technique
- Not safe for trapdoor or vintage rifles
- Premium price for specialty ammunition
