Xtreme defense lead free fluid transfer monolithic (xd ftm) is changing the way self-defense bullets are perceived.Like the xtreme penetrator, the progressive nose geometry allows for deep, straight penetration while creating a permanent wound cavity diameter exceeding that of most expanding bullets.Additionally, the bullet is solid copper, able to overcome barriers to penetration, is environmentally friendly and does massive tissue damage on impact.Penetrating barriers such as drywall or heavy clothing prior to impacting the intended target doesn't have the potentially negative effect on the xtreme defense that it does to conventional hollow point bullets.Coefficient: 0.17Bullet Type: Fluid Transfer MonolithicBullet Diameter: .452Weight: 220 grJacket Material: CopperCore Material: CopperSectional Density: .154Oal: .845Quantity: 50
