You're not imagining things -- and I've noticed from the beginning that fired/unsized cases would not accept bullets until re-expanded .... 0.3720" mouth as fired.
(ominous roll of distant thunder permitted here)
At the same time, I never get even the slightest sticky-case when seating loaded 0.3800" mouth diameters using gas bullets. Yet..... the strange mouth "crimp-looking" witness mark, and tight as-fired case mouth. Go figure.
I'm about to take a very brute force approach to resolving if/where there's chamber anomaly in all this.
Film at Eleven ....some time a week-10 days from now....
