Sig V Crown 9mm 115, 124, and 147gr JHP in Clear Ballistics gel. All of the Sig’s 9mm offerings tested. Two rounds in bare gel, two in heave clothing at 10 feet. All shot from a Smith & Wesson M&P compact 2.0 with a 4-inch barrel. I continue to have a problem with the chronograph and I’m going to have to find a remedy to the problem.
Let’s start off with the 115gr. The first round didn’t register on the chrony but penetrated to 12.75 inches and expanded to .64 inches. Round two had a velocity of 1229fps and penetrated to 13.25 inches and expanded to .64 inches. In heave clothing, the first round penetrated to 20 inches and expanded to .54 inches. Round two exited the side of the first block at 15.75 inches, expanded to .55 inches and was found laying on the floor.
The first round of the 124gr in bare gel hit at 1199, penetrated to 15.25 inches and expanded to .60 inches. Round two had a velocity of 1191fps and also stopped at 15.25 and expanded to .61 inches. The heavy clothing test was a little disappointing. The first shot had a velocity of 1195fps and passed completely through both 16-inch gel blocks and was not recovered. Round two penetrated to 17.75 inches and hit at 1213fps.
Now the 147gr loading. Bare gel shot penetrated to 18.75 inches and expanded to .58 inches. Round two penetrated to 18 inches and expanded to .68 inches. No velocity on either round. Like the 124gr, the 147gr was a bit of a disappointment. The first round had a velocity of 1007fps, penetrated to 19 inches and expanded to .50 inches. Round two hit at 1034fps but passes through 32 inches of gel and was not found.
Normally I would do a short barrel test but because of the chrony problem, I will update later when I have a chance.
