I imagine you are right about that, they would most likely hold their wieght and act like a heavier bullet in doing so.
I wish I had better luck with them in the three calibers I tried them in. Could never get them to shoot inside 1 1/2" and couldn't afford to buy more since they end up close to a buck a pop.
Better get yer yogi tag and video camera and get us some footage this weekend!
Good luck.
