We only started to see differences in performance in bullets when he shot through intermediate barriers such as laminated auto glass and sheet metal.
Doc, from your OP I assume the dismal .380 performance was also through the barriers, correct?
The .380 ammo shot at both bare gelatin and through 4 layers of denim failed to meet FBI minimums. Same with 2 layers of 5/8" sheetrock. We didn't bother to shoot it through windshield glass, as we wanted to move on to .223 patrol rifle tests and the 380 was clearly out of the running.
