Thread: 6.5x47 Lapua not chambering

Just a side track - What sort of micrometerare you using ?
mine measures 3 digits then the last one is .xxx5 or .xxx0.
So yours measures better than 1/10000 inch ?
It sounds as if your bases are now about.001" (a thou) bigger than when new.

Could your necks be stretching ? I have to trim between .005 and .010" off the end of my cases after 3 or 4 reloads. For some resson it varies aclot from case to case.
