Cor-Bon DPX 10mm 155-grain ammunition (brand part no. DPX10155) is built for shooters who carry a 10mm for its power and want a bullet that will not quit when the shot has to go through something first. Cor-Bon loads the Barnes XPB, a 100-percent solid copper hollow point with no lead core to separate from a jacket, because there is no jacket to separate from. Internal serration cuts, rather than the traditional external notches, let the bullet peel open into six even petals while holding onto virtually all of its original weight. That barrier-blind performance is what Cor-Bon built the DPX line to deliver, whether the barrier is auto glass, sheet steel, or heavy clothing. For 10mm shooters who want maximum penetration guarantees behind a proven expanding bullet, this handgun ammunition stands out as a serious defensive and duty load.

Key Specifications

• The caliber is 10mm Auto, a hard-hitting semi-auto cartridge favored for its power over 9mm and .40 S&W.
• The bullet weighs 155 grains, a lighter-for-caliber weight that Cor-Bon pairs with high velocity for flat trajectory.
• The bullet is Barnes’ XPB, a 100% solid copper hollow point, with no bonded core to separate under impact.
• Because the bullet is lead-free, it meets requirements in jurisdictions that restrict traditional lead-core projectiles.
• Internal serration cuts replace external notches, letting the bullet open symmetrically instead of tearing unevenly.
• That design lets the bullet expand to roughly double its original diameter into six sharp petals on impact.
• The XPB is engineered to be barrier-blind, retaining nearly all of its weight after punching through auto glass or steel.
• Each box holds 20 rounds, enough to load several magazines for practice or carry rotation.
• Cor-Bon packages this load in 500-round case lots for shooters who train with their carry ammunition.

When a defensive round has to get through a barrier before it gets to the threat, weight retention is not optional. Cor-Bon built the DPX line specifically for that scenario, and the 10mm loading gives it velocity most calibers cannot match.
