*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.
A coworker was curious about two loads he has in .357 Sig and gave them for me to try out. The one I will report on is the Hornady Critical Duty 135gr FlexLock in .357 Sig. Test gun used is a Glock 31 with a four and a half inch barrel shot into two 16 inch blocks of Clear Ballistics gel.
Round one shot into the bare gel had a velocity of 1210fps, penetrated to 16 inches, and expanded to .54 inches. Round two had an impact velocity of 1184fps, penetrated to 17 inches, and expanded to .51 inches.
Round one into the heavy clothing gel hit at a speed of 1184 penetrated to 16 inches and opened up to .51 inches. The second round had a velocity of 1174fps with 18.5 inches of penetration and expanded to .48 inches.
