[QUOTE="Derek M., post: 588643, member: 2693"] I guess I've been mistaken on Lapua brass. I was under the impression that their flash holes are drilled and no need to debur. I should have mentioned that I do size all of them in my die before loading so as to get consistency. I sent my dies back to the manufacturer with some fired cases and my measurements to ream the neck large enough to where I'm working with only .0025 less than a loaded round. A lot less brass working and fewer annealing processes necessary. I will add the expander button, resize each case, then remove the expander and squeeze the neck down again, ready for reloading. I've found this reduces runout by a substantial margin. Got the idea from this article: [url=http://www.6mmbr.com/TacticalFroggyA1.html]Bugholes from Bipod[/url] After my sizer die modifications, there is much less brass work-hardening and runout is near non-existent from what I can see on my gauge.
