mean bullets by Rock, Verified Owner, June 11, 2024
I love the bullet It is a very effective self-defense tool. I feel like if you can just show it to somebody. They would probably run

Features of Underwood Ammo Xtreme Defense .45 ACP 135 Grain Solid Nickel Plated Brass Centerfire Pistol Ammunition:

  • Flutes that force fluid inward to build hydraulic energy and expel it radially;
  • Consistent penetration and wounding performance despite encountering barriers via monolithic material and non-expanding design;
  • Lightweight - high energy, low recoil;
  • It does not rely on deformation for resistance in soft tissue, thus eliminating concerns of over-penetration resulting from a lack of expansion;
  • Barrier Blind - minimal surface area to increase the force at the point of contact and sharp cutting edges that defeat barriers;
  • Streamlined manufacturing process over original CNC design
