To compare, a 180 grain Federal HST JHP expanded to 0.56″ when fired into ballistic gel covered with 4 layers of denim, and. 40 S&W Corbon DXP bullets expanded to exactly 0.64″ whether fired into ballistic gel covered with 4 layers of denim or bare ballistic gel.

Thus, a bullet that maintains its integrity as it penetrates will tend to be a more reliable bullet when it comes to stopping a violent attacker.ĪLSO READ: Conyers, GA Parking Lot Robber Shot by Armed Crime VictimĪnother benefit of being made out of a single piece of copper is that the Corbon DPX exhibits reliable expansion, regardless of whether it first passes through an intermediate material such as heavy clothing. Penetration depth, in turn, matters because the only reliably way to stop an attacking criminal is to have the bullet penetrate deeply enough to reach and disrupt that criminal’s vital organs. Fragmentation can be a problem because a bullet that breaks up into small pieces will generally not penetrate as deeply as a bullet which maintains its structural integrity. This larger than normal hollow area is likely due to the fact that this bullet is made of copper, which is a harder metal lead, meaning that less metal is needed or desired in the part of the bullet that is to expand upon impact.īecause its bullets are made out of single pieces of copper, Corbon DPX doesn’t suffer from fragmentation problems that copper jacketed lead bullets can experience. I’m accustomed to the appearance of hollow point ammunition, but was amazed when I first held a round of Corbon DPX. Looking at the Corbon DPX, the first thing one notices is the massive hollow cavity at the front of the bullet. Instead, Corbon DPX makes use of Barnes homogeneous coppers hollow point bullets. What sets the Corbon DPX apart from most other self defense rounds is that it contains no lead. The “DPX” stands for Deep Penetrating X bullet, and it is available in a variety of calibers.
