I got a .22 for my 15th birthday but before that had a pretty powerful BB/pellet gun. A Crosman Powermaster.
I was also told not to point any gun, real or toy, at anyone and specifically warned that that could get me shot.
Not a fan of any of the airsoft or paintball type LARPing that entail shooting other people. Watching youtube vids of millennials having meltdowns and going postal on each other is kind of amusing, though.
