4. Basic measurements for the 8x58RD. Rim: .579. Rim thickness: .063 Base dia: .505.
5. Basic measurements for the 45x110. Rim: .608 Rim thickness: .070 Base dia: .505
Looks to me that any basic 45-90, 45-110, reamer would clean up all of the old chamber and rim, with the barrel rebored to .458 or .459 and shortened only enough to provide the needed wall thickness and recrowned it would seem a 45-90 or 45-110 would be feasible. Something to run by Jesse for sure though. I suppose one could drill and sleeve the chamber for something like the 40-82 winny with the rebore to .410, and shoot only black might be possible and less expensive than new barrel and all that is entailed with that. Good food for thought.
