I have an O.A.L. question regarding Sierra MK's, or rather to save any misunderstandings a C.B.T.O. (Case Base To Ogive) query.
Do any of you remeasure C.B.T.O. for every batch of bullets you get or just hope there're all the same measurement?
I've just acquired 4 boxes of .311 174gr SMK's and the packaging suggests 2 boxes are of earlier manufacture, there's an average of ten thou difference between them and newer ones.
