Okay Guys you have started something here with this thread. I have a Remington Hepburn action and I have been trying to figure out what caliber to make it. I already knew that I wanted to do it in an English Stalking style and was leaning towards a 38-55 but this seems to me to be just what I was looking for in a cartridge as far as pressure and shootability. Now the big question that I could use a little help with. What is the bore size? Any help or push in the right direction would be gratly appreciated.
