Well, gotta admit we've done similar here, with bad cartridges - dented, cracked case-mouths, pushed-in bullets, etc. We stuck them into the target backing at 50 yards, and hit the primer with a good .22 rifle. A loud POP! and a bigger hole in the target backer.
Not smart maybe, but we do take precautions.
Case and bullet always wind up well down-range.
Had a buddy shoot a full 12 oz. CO2 cartridge once, at about 25 yards.
It wizzed back and hit him in the chest. Now, that was STUPID!
