Mick, 10.5-11#? That ain't brisk, that's insanity. I'm getting a concussion thinking about it. It would probably put me back like that dude in the Nickudu files that built that 4-Bore with external hammers.

Rob, would that Heym be 500Grains' rifle? There aren't too many 600 NE's floating around in a Heym.
