9mm gel test: Underwood 115 gr Lehigh Extreme Penetrator HD

Underwood 115 gr Lehigh Extreme Penetrator solid copper projectile fired from Glock 22 with Lone Wolf 9mm conversion barrel into calibrated 10% gelatin. BB: 585.3 fps, 3.3" Impact velocity: 1,289 fps Penetration: ~30" of gelatin & 2.5 feet of water Retained weight: 115.0 gr No expansion. For comparison, we took a look at some cheap 9mm ball. The cheapest I could find was S&B 115 gr FMJ. It was almost exactly 100 fps slower and penetrated quite a bit less. I expected lower velocity and less penetration but not to that degree. It was also surprising to see that plain, vanilla FMJ produced more tissue disruption than the vaunted Extreme Penetrator. On my way out to test, I looked at my phone and saw that tnoutdoors9 had posted a video testing the very thing I was about to do. I was not thrilled, especially since he does such great work. It turns out that my test was a little different than his anyway. Take a look at his test too, if you have time: https://youtu.be/DYLbmSp5itA
