The video of the 50 is at:

There's two versions of the same video, with 2 levels of crappiness due to different compression settings:
50bmg_ar.avi, 6.9M
50bmg_ar2.avi, 11.0M
My son was running the camera, and the actual shot looks even more earthquake-like than it really is, because he jumped pretty good when that baby went off. "Awesome" is an overused word these days, but that 50 BMG is
awesome. Or in farmerj's words, "Mahhh Deuce! LOVVVVE the Ma Deuce!"
