Just finished up the testing of the 165gr 40 S&W Federal Tactical Bonded (LE40T3) round. Here are the conditions and results.
-300 feet above sea level
-Test rounds fired from 10 feet
-FBI spec Clear Ballistics gel block (more on this below)
-4 layers of denim
-1066 fps, 416 ft/lbs energy
-13.5'' of penetration
-Recovered weight: 161gr
-Average expansion: .66''
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.
Here's the video showing the test, the permanent cavity, and a discussion of the results:
