The Underwood .44 Remington Magnum 220gr Xtreme Penetrator from Underwood Ammo (Underwood part no. 841) is a solid copper, lead-free .44 Magnum load, sold in a 20-round box. Underwood pairs its own power and precision with Lehigh Defense Xtreme Penetrator bullets, which have a unique nose meant to maximize penetration and feed reliably. The blunt nose is designed for initial energy transfer and straight, deep penetration, and the cutting edges are meant to punch through entry barriers without deformation or deflection. Muzzle velocity is listed at 1,530 fps with 1,144 ft-lbs of energy. It suits shooters who want a lead-free monolithic bullet in a .44 Magnum revolver or rifle.

Frequently Asked Questions

What should I know before firing .44 Magnum ammunition from a lightweight revolver? Underwood notes that its .44 Magnum loads are produced within SAAMI specifications and carry exceptional recoil, and it prefers to see them fired from steel revolvers. In titanium, scandium or aluminum alloy frames it recommends only one or two rounds in the cylinder at a time, because recoil can loosen the crimp on waiting rounds and let a bullet creep out of the case. You can shoot them in a snub nose .44 Magnum, but a full cylinder may be hard to manage.

Is the Xtreme Penetrator bullet lead free? Yes. Underwood lists the bullet as solid copper and not containing lead.

How many rounds come in the box? The box holds 20 loaded rounds.
