The second .357 Sig load my coworker wanted me to try was the Speer 125gr Gold Dot. Test gun was a Glock 31 fired into two 16 inch blocks of Clear Ballistics gel.
The first round into bear gel had an impact velocity of 1415fps, penetrated to 14 inches, and expanded to .70 inches. Round two’s speed was 1409fps with a penetration of 16 inches and expansion of .68 inches.
I didn’t get a velocity of the first round in the heavy clothing but it penetrated to 18 inches and expanded to .58 inches. Round two had a velocity of 1425fps, penetrated to 17.5 inches and expanded to .56 inches.
