Loaded up some Hornady Critical Defense 45ACP 185gr JHP rounds, brought out the Clear Ballistics gel (calibrated to manufacturors specs), grabbed my Springfield Armory TRP (5'' barrel), and the video camera and here's what I found.

Hornady Critical Defense 185gr 45ACP Gel Test HD Video
The manufacture of the gel block, Clear Ballistics, claims their gel meets FBI specs for testing. I calibrate my gel per their specs prior to testing and use 4 layers of denim per IWBA protocol.
However, by no means am I saying this test is a substitute for the great work industry professionals like Dr. Roberts and others do. I'm just a shooter that likes to learn about the products I use.
