[QUOTE="mtJim, post: 2603296, member: 121886"] No sign of a donut on any cases I inspected. A 6.5 mm bullet slid through the length of the neck without any hang ups. Nothing on the teslong either. Expander stem looked good, rolled perfect across the table. Not a new piece of brass, but one that was fired in the old chamber. Resized it the same, measured .001 runout on the case neck after full length sizing. Seated a bullet and measured .005 on the bullet after seating. Same click and stick of the press handle at the start of the up stroke. If I run a loaded round back into the seating die (set at the same length it was when that round was assembled) I still get the click and stick on the start of the upstroke. That leads to to think that the full length sizing and case prep is good, the issue is in the seating stem. I’ll look into bedding it. That would be better than polishing with lapping compound?
