This business of rim thickness

[Oregon Bill]

I have been vacuuming up all I can read on the .50-95s, and just read the 2021 thread by nohorse on his Uberti Presidio, which apparently won't go into battery with a rim much thicker than .058, if I read correctly. Just for squirts, I rifled through the brass catchall bin and came up with a few rim thickness measurements of my own. Wish I had a bigger sample.
Bell .50-90, .060.
Starline .50 Alaskan, .066;
W-W .348 Winchester, .068;
Remington R-P .45-70, .066;
Bertram .43 Spanish, .083.

Looks like Roosterman has a similar issue with the .50 Alaskan rims in his '76. If and when I can drag a .50-95 to my house, I will test with cases made from Starline .50 Alaskan, the WW .348, and the Bell 50-90 and report.
