Found some scrap metal left over from when they built my pole barn. Had to do a test so I shot a piece with a Raptor and then with the old lead pellet. Wearing eye protection, of course. The Raptor went straight thru. The Copper Head just dented it with 10 pumps form my old 66. If I shoot mice or bird in the barn I got to not pump to the max! There is already a plugged 1/2" hole in the tack room where the kid missed a coon with a .22.
