Underwood Ammo Xtreme Penetrator 44 Rem Mag 220gr Solid Monolithic - Box or Case

The Underwood Ammo Xtreme Penetrator in .44 Remington Magnum is a hard-hitting hunting and defensive load built around a 220 grain solid monolithic bullet designed to drive straight through tough hide and bone.

Engineered for performance out of magnum revolvers, this load pairs a precision copper projectile with Nickel-Plated Brass cases for smooth feeding, reliable extraction, and added corrosion resistance. The monolithic bullet profile is shaped to maximize penetration while cutting a consistent wound channel, making it a strong choice for medium to large game hunting and serious woods-defense applications.

The cartridge pushes the 220 grain bullet at a rated 1530 fps for 1144 ft lbs of muzzle energy, putting it firmly in supersonic territory with the authority expected from a hunting magnum. Whether you are loading up for a hunt or guarding against the heaviest North American predators, this load delivers the kind of impact the .44 Rem Mag platform was built around.
