This is a video from RatedRR (more nudity than an R movie, but not a full-blown porno) of a bunch of different ammo types being fired underwater in super slow-motion (and high definition). Hollow points, full metal jackets, you name it. "Rubber bullets?" No rubber bullets. "Powerpoint presentation bullets?" Okay, no more questions from you. Also, you can see the dude's nips several times when he's firing, so this could serve as one of those "bikini chicks shooting guns" videos but for the ladies. *rubbing own nipples* You ladies like what you see here? "No." God, me neither.
Hit the jump and +10 your bullet knowledge.
Thanks to Tim, who agrees shooting bullets underwater should only be attempted during adult swim.
