Thank you all for all your answers...
Quite a few years ago, I loaded up some Cast Performance .41/255s and shot them though 5 water jugs...after exiting the jugs, the bullet went through a 3/4" piece of concrete form plywood and the buried itself 1/2 way into another... The bullet lost the gas check and that was about it...
It would be interesting to put these bullets on a hardness tester to see what they run...
