Unfortunately, my chronograph was not working and I was not able to get the velocity of the rounds that impacted the gel. The five shot average was taking the following day. I got a five shot average of 1160fps with a low of 1153 and a high of 1170fps. Point of impact was just a little high at 10 yards. The BB shot was a little deep and just under4 inches.

Five rounds off hand at 10 yards

The first round in the bare gel block penetrated to 12.25 inches and expanded to .75 by .74 inches. The recovered weight was 167.9 grains. Round two penetrated to 13.25 with a recovered weight of 168 grains. Expansion was .72 by .68 inches.

With the heavy clothing shots, round one expanded to .70 by .65 inches and penetrated to 13.75 inches. It’s recovered weight was 169.5 grains. The second round penetrated to 15 inches with a recovered weight of 196.6 grains. Expansion was .70 by .64 inches.
