[QUOTE="QuietTexan, post: 2641378, member: 116181"] It seems like you're focusing heavily on overall case length and not considering variance in headspace length in new cases. I've measured more than 0.003" variance in lots of Lapua, Peterson, Nosler, Hornady, Norma, Starline, Remington, and ADG. Usually more along the lines of 0.004" over a group of 50-100 cases. Moving a shoulder .002 will change the length of the case, trimming too soon or when new removes material that might be needed to keep the cases longer once the shoulders move forward. [/QUOTE]
