[QUOTE="Bart B, post: 755253, member: 5302"] Will these issues of full length versus any other way ever end?????? Prolly not. Sierra Bullets has been full length sizing their fired cases used to shoot their bullets for quality control since the 1950's. I doubt anyone shoots 'em any more accurate than they do. Nowadays, they use Redding full bushing dies for cases they're made for, standard Redding dies for all the rest. Benchresters pretty much moved from neck only to full length sizing with bushing dies not too many years ago. Their smallest groups didn't get any tinier but their largest ones did; by quite a bit, too. So the average group size got smaller. High power match rifle shooters have been full length sizing their cases for as long as Sierra has. Many tests with these normally shoulder fired rifles clamped in machine rests have produced groups smaller than current bench rest records. Minimal fired case sizing helps. Don't reduce the fired case body diameter nor set its shoulder back more than 1 or 2 thousandths inch. Use neck bushing dies sized about 2 thousandths smaller than a loaded round's neck diameter. Choose the tools and procedures your feel most comfortable with. Note that if one doesn't use any set of tools and techniques correctly, it'll not produce acceptable results. Learn how cases exactly fit the chamber when they're fired with and fired case sizing method; that'll help you decide what's best to meet your objectives. Regarding objectives, list them in order remembering if you move a lower placed one up the list, some higher ones above it have to come down. [/QUOTE]
