RE: paintball..... dangerous to skin.... haha
650 fps? That kid might as well have shot you with a round ball muzzleloader...
We shot around 215 fps in the indoor range down here back in the day...
Outside we usually shoot around 300...280...in that range...usually won't let us go 300 though cause they chrono every time...
Ain't no-tellin how hot we shoot when we play pick-up games at the house....probably 315-325...and that crap hurts...
And I don't layer up anymore either...makes some nice witness marks...that's for sure...
