The CorBon DPX 9mm +P (115-grain solid copper expander) was tested in ballistic gel to evaluate its performance from two common carry guns: a compact Canik METE MC9 with a 3.1-inch barrel and a full-size Glock 17 with a 4.5-inch

Overview This ballistic test covers an older lot of CorBon 357 SIG 125-grain jacketed hollow point (JHP) fired from a 4.5-inch barrel. The goal was to measure real-world velocity, study its behavior through clothing barriers, and examine penetration and expansion

Introduction — Why this test mattered When defensive ammo gets mislabeled, trust takes a hit. After Cor-Bon corrected a packaging error and sent the intended 125-grain +P rounds, I returned to the range to run a proper ballistic gel retest.
