Underwood Xtreme Defender 10mm 115gr Solid Copper 20rd Box

The Xtreme Defender is Underwood's fluted solid copper defense load, and in 10mm it pushes a light 115 grain bullet to about 1700 fps. Instead of mushrooming, the fluted nose uses that speed to force fluid outward and cut a wide wound channel, with penetration rated up to 18 inches.

Because it does not depend on expansion, wallboard, sheet metal and auto glass do not plug or deform it the way they can a hollow point. The bullet is lead free, and the load comes in nickel plated brass, 20rd to the box. A good fit for a 10mm carry or home defense pistol where you want barrier performance with less recoil than heavy loads.
