One of the best videos I have seen on this subject. Your video gives a hint
that I’m not sure you realize. It happened to me with a target. I purchased
one that person wasn’t using. I told them if it didn’t go straight through
it and I could pull it out I would buy it. They set it on the ground I shot
365fps bolt. It went about half way into it I walked up and pulled out with
2-3fingers..I set up at home securing it. When I shot one I couldn’t get it
out, destroyed bolt trying. shot an other with same issue. Your fist target
had solid hold. second one teatered maybe just enough to disperse energy so
it didn’t go through. I will be trying it without stabilizing it solid like
on your first part. I bet letting it wobble a bit it the answer. I’m on my
sixth target this week. 3 home made, 2 store bought, this one with 5 holes
in it.
