Question: The specs for my mold I got for the 375 Win (and 38-55) throws a .379" bullet. I'm going to be using an alloy with a BHN about 18. Specs on the 375 list a .376" bullet while the 38-55 list a bullet diameter of .377". Will I need to size them down to .377"or .376" prior to loading. Bullets will be powder coated and not lubed.
I think I just answered my own question. I went down and slugged my bore and it measures .376" I believe I will need to size them down some. I'm thinking .377"! What say you?
