How about a ½ inch thick plate steel with a ½ inch hole?
The HyperShocks trip livers will hit the steel and cycle under resistance, which would cut skin but not steel. The blades would deploy on the backside of the plate. Opening the blades with a cut DIA 1 3/8 up to 2 ¾. The Slick Trick would loose all of the blades or stop dead. I know we can shoot for this hole at 40 yards with the x-ring machine that will test accuracy. We can also put some of that ballistic gel on the backside of the steel to measure the volume of area that has tissue damage. Lets do it!
I will help you Big Bull PM me and we can try to set it up.
