Ah, just lube em up and run them through the .375 die. I run lubed .458WM cases through my .416 Taylor die to create the Taylor cases on my 45yoa RCBS JR (not Rockchucker) press. Maybe the sharper Ruger shoulder might be an issue and maybe not? Lube em up and try it! Live on the edge!I do have the cases. When I got the rifle, he gave me some fired brass as well as 50 straight ones. When I asked him about it, he said he just would use lots of case lube and the .375 die. I kinda figured there may be intermediate steps, which is why I thought I would ask on this reloading forum first. I did not want to re-invent the wheel if someone had already done it.
