LOL Richard Ryan is the man:

I hate to think how much even one round for that cannon is.  Makes his Barrett .50 BMG look like a pea shooter.

2:10 – Wow as usual the slow motion footage was amazing… seeing that round break apart is something else.  So much debris coming of the barrel after it too wow.

2:24 – LOLOL peeled that iMac’s wig back.

When ever I see Richards videos I can’t help but think he didn’t get the “No Right To Bear Arms” memo everyone else in the state of CA got. :P
