[QUOTE="str8shoot, post: 433454, member: 26034"] While I too get some loose pockets with win brass, it won't be every piece. 73 grains of H1000 is a mighty stiff charge in a 7mag. 71 is what I found to be max in my rifle with a wlr primer. Berger has 69.5 as max which is conservative. If your primer pockets were tight to begin with and are loose now you got excess pressure stretching things out. You are 3.5 grains over book so you know you gotta be more than a little warm. Nice thing about the bergers is because of the high bc you don't have to drive them so fast to reach way out there. I'd find another accuracy node with less powder imo. [/QUOTE]
