Steve,
Great report, it's nice when you getting something to work right.
I shoot some bore diameter jacketed bullets and they are groove diameter by the time they leave the barrel. Smokeless will upset both jacketed and lead bullets just fine.
I bought some of the Hornady .405 brass and sent it to a fellow who has .38-72 dies and he ran it through for me. I don't need to re-size because I breech seat my .38-72 but the Hornady brass is good stuff. If you want to try a few let me know and I'll send some down.
