Thanks for the slo-mo video! Just seems to be more of the same old same old, though. The ejector is hitting low at or about 7:00 o'clock on the case head; and the ejector claw isn't holding onto the rim either tight enough, or for long enough to correctly spin the brass. While all this is going on I, also, suspect that the extractor is, 'chattering', too, and the head of the EDP rod is taking a beating.
(Right or wrong, time will tell.)
