Ryan it's a heavy-a** gun. As in really heavy. I'm almost positive John Getz has the dimensions. As mentioned above it's got a monster breach, then a good taper (with a lot of weight in, say, the breech 12" to 16" of barrel) but the remainder of the barrel does not have the big ridiculous taper/flare you see on a lot of modern stuff. I think I have the dimensions every 2" stashed away somewhere but it would take me some time to find them. I'd ask John - I feel pretty positive he has them.
