[QUOTE="Bart B, post: 513919, member: 5302"] Surely you know that all rimless bottleneck cases are cockeyed in the chamber a tiny bit; both when loaded and moreso when fired. Don't you remember back in basic training that the back end of the case body is pressed against the chamber wall at one point by some force? The back end is off center by half the difference between chamber and case diameter at its pressure ring. And the case shoulder perfectly centers in the chamber shoulder. Then why do the most accurate rifles I know of shoot best when the case fits the chamber "...like a turd in a punch bowl." That quote's from the man who professionally loaded and tested probably more ammo than all those on this forum combined with some of the most accurate bullets on this planet for over 30 years. Nothing shot as accurate as properly full length sized cases with "lots" of clearance between case and chamber......except at the back end, naturally, as mentioned above. I've tried every fired case sizing tool type and technical process man's invented. Nothing shoots as accurate as full length sized cases done so the right way. [/QUOTE]
