Lead has a very high density and does a great job at penetrating deep, but it lacks any real structural integrity.Lead is quite soft, especially when compared to copper.Our solid copper wfn line of projectiles have a tensile strength of 10-20x greater than conventional lead projectiles.This massive increase in strength allows our wfns to punch through the hardest of bone with little to no deformation, which nearly eliminates the possibility of deflection due to the projectile deforming.Coefficient: .148Bullet Type: Wide Flat NoseBullet Diameter: .400Weight: 190 grJacket Material: CopperCore Material: CopperSectional Density: .170Oal: .755"Quantity: 50
