When I ordered this form Bone Frog Gun Club I thought they were HST’s. Not that I was disappointed, just not what I was expecting. I guess they get overshowed buy their HST line but it should prove interesting none the less.
Four rounds fired into two 16 inch blocks of Clear Ballistics gel form a Glock 19 with a four inch barrel. Two rounds through bare gel and then two through heavy clothing.
The first round in bare gel had velocity of 1078fps penetrated to 11 inches and expanded to .61 inches. The chrony didn’t pick up the second shot but it penetrated to 12 inches and expanded to .62 inches.
The first round in heavy clothing has an impact velocity of 1074fps penetrated to 14.5 inches and expanded to .61 inches. Shot number two hit a 1097fps 13 inches of penetration and expansion of .58 inches.
