Underwood Ammo Handgun Ammunition Features This Underwood .44 Mag load drives a 245 grain full metal jacket bullet to 1450 feet per second generating 1144 ft lbs of muzzle energy for serious stopping power on target. The bullet s copper and lead construction at a diameter of 0.429 inches is built to penetrate deeply while holding together through impact. A sectional density of roughly 0.190 reflects how well the bullet s mass is distributed to maintain penetration along its path. This combination of velocity and bullet design makes the round a proven choice for hunting medium and large game. The nickel plated brass case resists corrosion and feeds smoothly through revolvers and lever guns chambered in .44 Mag helping ensure reliable cycling shot after shot. Because the load is supersonic it is also rated safe for use with a suppressor giving shooters the option to reduce report without sacrificing terminal performance. Each box contains 50 rounds packaged for hunters and range shooters who go through ammunition quickly.
