I am thinking of having a barrel chambered in 6.5 Creedmoor for one of my SA actions that is magazine fed with a COAL of 2.850". I would like to shoot the 140 - 147 grain bullets in this rifle but need help with what reamer specs will be best. I don't mind turning necks so was thinking of going with a .295" neck but not sure how much freebore I need? Any recommendations on reamer specs would be great. Thank you in advance.
