While i have never been stupid enough to try that... hey the bb gun and 22s on a board sound like a hell of an idea!
But nothing worse than shooting each other with bbs as a kid.. too poor to afford paintball gun.. so what was the next best thing.. no face shots or crotch shot all else fair game.
Wow that was dumb..
Me and a friend used to have "BB gun wars" in the backyard, 3 pump limit, no face. Yeah, it was stupid.
Hitting rimfire bullets with a hammer, done it, also stupid.
Filling empty CO² cartridges with 50/50 black/smokeless powder and sticking cannon fuse in the and burying them in the backyard, lighting and running... EXTREMELY entertaining, also stupid, also painful after a neighbor called one of my parents at work...
No scars, no permanent injuries, have probably used my luck quota for the rest of my life...
