[QUOTE="The Oregonian, post: 1652834, member: 51405"] My experience is that stainless tumbling for very long can cause the necks of the case to become thicker or flare out a bit...I don’t know which bc sizing should fix a flare and the case mouths measure about the same size with a micrometer. My strong guess is that it is thicker at the very end and it is hard to pinpoint just those handful of .001’s on the micrometer. If I place calipers around the middle of the neck it measures the size of my neck bushing, and if I slowly pull the case out vertically and let it adjust the calipers it measures .003-.005 thicker right at the end of the neck right before it comes out of the calipers. The end result is that cases with bullets seated won’t Chamber bc they won’t go into the neck. I need to turn the necks to get rid of it and have switched to sonic cleaning, which solved the problem.
