This is 40 S&W Corbon Pow'RBall 135gr. Ammunition. The Pow'RBall is a hollow point bullet capped with a polymer ball giving it a "full metal jacket", or rounded "ball" profile. The polymer ball is smooth and slick, so it is a 100% jam free round. The lead core is shaped into a specially designed cavity. Upon entering the target, the polymer ball promotes controlled expansion of the bullet. The resulting classic mushroom shape dumps all the available energy into the target. This round nose profile is unaffected by heavy clothing, glass, or sheet metal. Recovered bullets from test medium have excellent (80% or better) weight retention after 12 to 14 inches of penetration.
