[QUOTE="Laguna Freak, post: 2938299, member: 87188"] My experience with case head re-sizing: I bought the Cortina Precision expanding mandrel die for WSM and re-sized 20 cases. Interesting thing is even though the die ID measures 0.551", it wouldn't get my case heads consistently down to 0.555". I kept getting the occasional 0.556" even after working the brass in the die a few press cycles. 0.556" was still a snug bolt closure even after bumping the shoulder back to my chamber's 1.740" = 0.002" clearance. I had to cut the top of my shell holder down about 0.030" to get 0.555" which chambers nicely. Hoping it didn't make primer pockets too tight. [/QUOTE]
