40 or so years ago my son and Ishot primer powered .38 Specials out of plastic cases, don't remember what the bullets were...maybe re-usable soft plastic wad cutters. Shot into a cardboard box in the the fireplace with a hanging doubled up towel to catch bullets.
We used to shoot a neighborhood .22 match in the basements during the Winter using my Ruger Standard pistol and a .22 bullet trap - 2-3 Dads + 3-4 kids. There were Medals for the winners..I might have one laying around.Fun, family bonding and lifelong gun safety lessons taught.
No eye or ear protection worn but then no one used such in those days.
