O.K. you kind knowledgable people. I want to make sure I have this right. I just received my lapua brass and was measuring the outside diameter of the necks with a electronic RCBS caliper. The average dimension was .268. My question is, after I fire a few cases, what bushing size under my hard neck measurement should I use? I am not going to neck turn. Do I want to size .001 under, or leave more? Keep in mind I have not reloaded for my 6BR yet. It should be here next week.I have been studying and reading for the last 7 mos. to prepare for reloading my new 6BR. There is just so much information that is hard to find a close place to start. Thank goodness for this websight and the people involved.
