Sig 115 gr V crown fired from 4" barreled Glock 22 with Lone Wolf 9mm conversion barrel through 4 layers of denim into calibrated 10% gelatin.
BB: 584.2 fps, 3.3"
Impact velocity: 1,242 fps
Penetration: 14" of gel and 12" of water jug
Retained weight: 115.0 gr
Max expansion: 0.554"
Min expansion: 0.429"
I’ll probably test again with bare gel and with denim and a short barrel.
