And 165 gr tests:
The denim is included as part of IWBA test protocol to represent heavy clothing. Some designs, especially older ones, have trouble expanding after passing through heavy clothing. I'm confident that the Norma JHP would have expanded in bare gelatin but almost anything will. The denim indicates that it might not be the best option for defense. I wish I had the time and resources to do a full battery of tests including bare gelatin, denim, sheet metal, auto glass, and wall board with at least five shots each like professional labs do but I just can't.
