Graham, I always enjoy your posts and the depth of your knowledge. The Bridger barrel has a slight taper to it. I measured it at the Helena museum last September at 1.185 ahead of the snail and 1.120 at the muzzle. I just looked at my photos I took of Greg Roberts tracing and measurements of the Bridger when they had it at the GRRW in 1975, and he shows 1.175 ahead of snail and 1.125 at muzzle. Carl Walker who handled the Bridger Hawken at the GRRW and built some of their commemoratives told me the barrel is not tapered. Carl said you can make that much difference with a file. That is half the thickness of a dime per side in 32 5/8", the plug added another half inch to 33 1/8" per Greg. Doc White shot the Bridger Hawken at the Ft Bridger Rendezvous and I think the bore is about .52 caliber. There are seven lands and grooves. One land is cut half away from the breech about half the length of the bore where the cutter got out of the groove and rode up on the land. The muzzle is not square according to Greg's drawing, though I did not notice that.
