[QUOTE="Barrelnut, post: 1416253, member: 74902"] I'm with Phorwath, there may be an issue with your chamber. I may be big in the body area. Have never seen new Hornady (or any) brass split in the body like that. Now your Lapua brass is only going 7 firings... Are you just bumping the shoulders back .002 or so when you FL size? I assume you are. The Lapua brass may be thinning at the web so fast because the die is squeezing so much brass up toward the neck on each firing. it is squeezing so much toward the neck, because the chamber is allowing the case to swell so much. Make sense? Also how much were you having to trim the necks on that Lapua brass? The brass that thins at the web, ends up being trimmed off at the neck. Thats the way I understand it anyway. [/QUOTE]
