Walnutred makes a good point, but I think we're going to find .361" is a good number-----at least that's the bullet diameter. Perhaps not coincidentally, it's also the bullet diameter for the .38-44 S&W---as in the cartridge Ira Paine designed---used in the New Model #3 Target-----with the cartridge case the same length as the cylinder (bullet seated entirely within---as in zero throat---as in super accurate and (supposedly) set records that (supposedly) still stand today---never mind I've never been able to find them---and never mind I haven't looked all that hard.
