Measured some cartridges - all in mm:
Cartridge - rim diam. - base diam. - rim thickness
11.5x65R /.450 Exp. - 15.50 - 13.78 - 1.06
11.15x60R Mauser - 14.88 - 13.06 - > 2
.45-70 - 15.15 - 12.74 - 1.76
I would not expect any original cartridge with Mauser base:
a) base diameter too narrow
b) most of these were bottle-necked
My guess still is this was a .450 Express that at some time was made to fit .45-70 cartridges - clever Bubba solution...
Comparing cartridges, only the recess for the rim needs to be cut deeper - maybe a .45-70 reamer wasn't even needed.
A fired .45-70 case should tell the story.
I can't think of any other cartridge that might fit, but I hope to get hold of a pre WWI G. Roth catalog later this week, maybe there are more suggestions.
