[QUOTE="Bart B, post: 666090, member: 5302"] Check out the section starting with [B]Custom Dies Work Best[/B] in this site: [url=http://www.6mmbr.com/gunweek041.html]Speedy's 6PPC -- The Art of Accuracy[/url] The reason they full length resize is to prevent interference between case body and the chamber wall that can cause the front of the case to no longer center perfectly up front at the chamber shoulder when too little clearance happens with neck only sized cases. Typically, a custom sizing die will reduce the 6 PPC case diameter at the shoulder .00075" to .001". The die will also allow for a little bit of shoulder bump. Redding full bushing dies do this very well for other cartridges, and even as much as a 2 thousandths diameter reduction in fired case body diameter doesn't hurt one bit for 30 caliber cases.
