*Note* This test was conducted with Clear Ballistics Gel. Clear Ballistics is a synthetic gel and does not correlate with Organic gelatin like Vyse Ballistics gelatin.
Today I had the opportunity to shoot some Hornady 135gr FTX Critical Duty Into some 10% Clear Ballistics gel. Test pistol was a Sig P229 with a 4-inch barrel. The rounds where shot into two 16 inch blocks of Clear gel stacked back to back for a total of 32 inches.
The chrony didn’t pick up the velocity of the first round shot into the bare gel and it exited out of the side of the gel block at about 15 inches and expanded to .44 inches. The bullet was found on the floor after hitting the rubber backstop. Round two penetrated to 18 inches with a velocity of 977fps and expanded to .44 inches also. I decided to shoot a third round and it stopped at 18.5 inches, expanded to .46 inches with an impact velocity of 997fps.
The first, and only, round fired through heavy clothing completely passed through both gel block and was not recovered. At this point I decided to stop the test and save my gel for testing something else.
I became curious as to what would happen I the polymer plug was removed and if it would change its performance. I fired one shot into a bare Clear gel block at 10 feet. I didn’t set up the chrony but penetration decreased to 15 inches and expansion increased to .52 inches.
