[QUOTE="Lefty7mmstw, post: 1026948, member: 48043"] [LEFT]Speed limits guys... Get it over a chrono. The 7rem has been backed off a bit pressure wise since there are a lot of variances out there in chambers.... Get her to the speed she should be at without any extractor marks or ANY noticeably heavy bolt lift and you should be good to go. The 7rem isn't as fast as the 7stw or 7rum but she'll still get the job done well way out there with careful feeding. As to primers, you'll often see a bit of extra headspace cause this, as the primer gets re-seated when the casing fills the chamber. The only time a primer is anywhere near reliable is when you are using brass formed to your chamber with a minimum resize. Even then I consider it a secondary indicator.[/LEFT] [/QUOTE]
