That'll learn 'em sumpin' good...The Lucky Mofo.

I fired an AR-50 once.
Once.
The muzzle blast blew the ear muffs back off my head and the bullet made a neat little hole in the black part of the paper target down range. I got up, said "Thanks!" and went back down to my end of the firing line.
Figured I'd 'been there, done that.'

Kinda like the time I fired a .505 Gibbs only the AR-50 was propped on sandbags on a card table so I didn't have to pick my ass up out of the dirt afterwards.
