Re: 7 wsm coal
First let me say that my 7mm WSM is a single shot with a long action so total cartridge length was not dictated by mag length or action port length. When I was in the process of building my 7mm WSM I called Dave Kiff at PT&G and he recommended a .190 freebore for the 180 Berger which is what I went with and my loaded rounds measure 3.135".
