Okay, not a big shotgun enthusiast. Thought I'd just FF through this one so I could say I watched it. BUT,
Saw the first close up slo-mo of the action and said, STOP THE PRESSES. (As I said, I don't know a whole lot about shotguns.) Wow, the whole barrel recoils. Neat. Of course as, Larry Potterfield points out there is a some dangers in that type of action, not to mention it was recoil heavy.
