Otto,
I think I remember your 9.5x47R from the auctions-nice.Since the groove diameter is .417",bullets shouldn't be much of a problem.I suspect a standard 416 bullet,"as cast"diameter will be close enough.Since you are listed as "chipmaker",I thought you might be a machinist.If this is so,you should be able to make button die/punch to make"A"base cases and "face off" 416 mold block to get the weight bullet you need.As best as I remember,the cases with the 9.5 were set up to headspace on the neck,so the rims were likely only turned to diameter and not modified to "A"base.As I recall also,your 9.5 came with dies. If this is so, they can be used to make cases from 45-70(normal rim)to fire form in the 10.5 by trimming to length and size til the rifle just closes.This should result in cases that headspace on the shoulder.Since you have two chambers,these cases may or may not work in both.If you modify the rims to "A" base,this shouldn't be s problem. This seems like a lot of fun,I wish it were my project.
