[QUOTE="can1010, post: 2108595, member: 43193"] you need to remember the freebore is on a chamber drawing not the case specs. if you have a .090 fb. you need to add the neck chamfer which is .016-.017 then the chamber neck is normally .010 longer so add that and the saami drawing is a 1degree angle so you can add another .015 to that. so add .090+ .016+.010+.015=.131 total now add case length and bullet noes to get a rough oal. that will put you at 2.990 touching now subtract distance off lands and different nose lengths. these # are berger 180 hybrids. you are fine with the reamer you have. hope that helps [/QUOTE]
