[QUOTE="RockyMtnMT, post: 1215255, member: 7999"] My experience with the Lapua brass is that you have to almost do something wrong to get loose primers. I am not as OC as you are Paul, as I have not measured case heads to see how much expansion took place. I work on the feel of seating pressure of the primers. The Lapua brass will take many firings on max load before you notice loose primer pockets. I have seen heavy extractor marks on the case head with no noticeable change in primer pocket. In my personal rifles I am ok with a slight ejector mark on the case head for top performance. On customer rifles I will back down from the slight ejector mark. My 338 just got done as well and has about 15 rounds down the barrel doing break in and case forming. Mine is a 40* shoulder. Hoping to get out and shoot somemore this week. Steve [/QUOTE]
