Wilson Combat's loading of the 115gr Barnes all-copper TAC-XP bullet turned in very consistent performance in some informal testing through four layers of denim. Whether fired from the 3" barrel of the Chiefs Special 9, John's 4" Wilson X9 test gun, or the 5" (actually 5.31") barrel of a Glock 34, the bullets penetrated between 12 and 14 inches in a
Clear Ballistics FBI block and expanded to look like advertising photographs.
Each inch of barrel just seemed to add about a half inch more penetration, and they all expanded fairly early
The top two are the Wilson-loaded 115gr +P 9mm bullets. The lowest one is a .45ACP 185gr +P Barnes TAC-XP from a Carry Comp 1911 built by
Chuck Warner. It also penetrated 13" and expanded perfectly. The lead-cored projectile, provided for scale, is a 10mm Auto Critical Duty bullet that was pulled out of the second block, having penetrated about 20" of denim-covered gel.
