Underwood Ammo’s +P Xtreme Hunter loading in .45-70 Government (brand part no. 908) loads a 325-grain solid copper bullet at increased pressure, built for hunters who want the maximum penetration their lever gun can deliver. Rather than a jacketed bullet designed to mushroom, the Xtreme Hunter is a copper solid, machined to hold its shape and drive a full-diameter wound channel straight through the target instead of expending energy expanding. The +P loading pushes that solid bullet to higher velocity than Underwood’s standard-pressure .45-70, adding even more penetrating energy for the biggest, toughest game. For .45-70 hunters who want the top end of what their lever gun can produce, this rifle ammunition is built for that job.
