I loaded some Extreme 200gr plated RN with PMC brass. The case walls are quite thick compared to Winchester brass I loaded prior to the PMC. I readjusted the seat/ crimp die. I should have measured the case lengths, I adjusted for a shorter case .892" not knowing this brass had length variations from .890"-.897
Here is what happened when I came upon a long case,
This round would not chamber in the barrel, it headspacing off the wrinkled copper plating.
Here is the round adjusted for the .892" case length,
