Product Overview
Underwood's +P 325-grain Xtreme Hunter is a solid copper .45-70 load made for medium game, large game and personal defense. Underwood machines the bullet from solid copper with no lead core. It leaves the muzzle at 2,275 fps with 3,736 ft-lbs and has a G1 BC of .23.
Zeroed at 100 yards, it drops 7.9 inches at 200 and 29.1 inches at 300. From a 200-yard zero it drops 17.2 inches at 300, and it reaches 200 yards with 1,909 ft-lbs.
If you're cross-shopping, Hornady's LEVERevolution 325-grain FTX shares the bullet weight and the same G1 BC but starts 275 fps slower, so from a 100-yard zero it drops 10.9 inches at 200. Federal's Fusion 300-grain SP is slower again at 1,850 fps on a higher G1 BC of .29, dropping 23.8 inches at 300 from a 200-yard zero.
- The most muzzle energy of any .45-70 load in the line-up
- Solid copper with no lead core, so it is legal where lead ammunition is restricted
- Still moving at 1,626 fps at 200 yards
- Loaded above standard .45-70 pressure and marked +P, so the rifle has to be rated for it, and Underwood rules out antique rifles
- Kicks about 13 percent harder than Hornady's LEVERevolution 325-grain FTX at the same bullet weight
- A hunting bullet, so target shooting is not what it is for
