Just a sample of load data: 160 gr Barnes TSX seated .050" from lands, H4831 52 gr (min. charge according to Barnes manual). R-P case resized .004" back from fire formed, WLRM primer. Results = ejector pin mark on case head along with significant "smiley face" (and horrible accuracy).
150 gr Swift Scirocco seated .030" from lands, H1000 68.4 gr (min. charge according to Swift manual), W-W case resized .002" back from fire formed, WLRM primer. Results = ejector mark on case head and stiff bolt.
243winxb, I'm hesitant to load any higher to fully expand the case as you recommend, along with the results above I've also had overpressure blowing the ejector pin into the bolt head with another min recipe.

So the question still remains, is .021" head to shoulder datum excessive causing my overpressure problems?
