As kids we drilled holes in plywood and put 22 shells in the hole. Then we would target shoot with pellet guns. Destroyed many pieces of plywood. Lots of fun.
As a young (very young) kid I dumped a case of shotgun shell power in to a hole, covered it with the shot made a paper fuse as new was all set to “touch it off” when mom found out what I was about to do. Yep, it never happened.
