About a 1:4 scale model, ie 3inch to the foot... still a handy enough caliber I'd have thought.... A 12 pounder is about a 72mm barrel bore (rough estimate seeing as a 6-pounder is 57mm), which brings a model in at around 18mm, so you'd be able to run shotgun cartridges in it, if you derate the cartidges a bit (lets face it a flash, a bang and something flies out of the end and hits a target 30 feet away is plenty from that sort of thing surely) you should have no trouble... My dad's favourite shotgun weighed less than six pounds so 17 lbs of brass should be able to handle a half charge without any trouble at all.....

I had no idea that a 12-pounder barrel weighed as much as 800 pounds! Stay un-reconstructed - we like you that way! How is you arm treating you? Cheers!
