I did some gel shooting today and after I was finished I decided to shoot a round off that I had laying around. A Speer .45 ACP 200gr JHP. Yes, the legendary Flying Ashtray. I only had one, unfortunately, so I could not do a proper test.
One round in Clear Ballistics gel out of a Sig 1911. Impact velocity of 984fps and it expanded to .75 inches! Just look at that big flat bullet. However, that large expansion had a cost of only allowing it to penetrate to 11 inches.
I wish I had more so I could test it properly. I’m going to look around and see if I have more laying around.
A member from the Beretta forum was kind enough to donate his last six bullets so I could give it a proper testing. Not having enough to do a proper load development I decided to go with 7.8gr of LongShot. The manual said I should get a little over 1000fps. I ended up just a little short of that with an average of 926fps. In this test, I used an HK USP .45 compact with a 3.78 inch barrel. I probably should have used my 1911 but I just wanted to use something different.
I didn’t get velocity on the first round fired into bare gel but it penetrated to 9.75 inches and expanded to .78 inches. The second round had a velocity of 954fps and penetrated to 11 inches with an expansion of .72 inches.
Only one of the bullets fired through the heavy clothing registered on the chrony and it had a velocity of 898fps. Unfortunately, both of the bullets passed completely through two 16 inch blocks of Clear gel. One of them bounced off the backstop was found on the floor. The hollow point was completely clogged with clothing and no expansion.
I decided to fire the last two rounds in bare gel instead of trying it in the four layer of denim. So number three in bare gel had a velocity of 910fps and penetrated 10.25 inches with an expansion of .76 inches. The last round penetrated 12 inches, expanded to .73 with a velocity of 944fps.
