[QUOTE="Edd, post: 1421930, member: 30592"] I think I finally figured out you are calling a SAAMI reamer a "0 freebore reamer". Originally I thought you were talking two different reamer specs. A 7mm WSM SAAMI chamber isn't a true "zero freebore chamber". The shape of the throat causes you to have the same amount of space as you would have if you had .0477" of cylindrical freebore .0005" larger than bullet diameter. That will put your bullet contact point about 2.185" from the bolt face. Now add the .852" bullet nose length to that and you are real close to the 3.050" OAL length you currently have. [/QUOTE]
