[QUOTE="LRHWAL, post: 228319, member: 5418"] AJ, Fired cases measure .340 at the largest point (see below). Loaded round is .333 (tops.334). I size for 3 thou tension, so I'm at .330. Sizing down 10 thou which in my (possibly ignorant) opinion is too much. It generally wreaks havoc with runout. Fired case necks are ( ) shaped, although that's a bit exaggerated. Rifle shoots 1/2 MOA most of the time out to around 300 yards, but I tend to get the odd flier (technique or really bad runout?). I also expect better with the rifle and the rest of the loading process I employ. I haven't had the runout gauge long enough to check that properly. I'm just keen to make sure that it's "right". Most of my buddies would call this a "non-existant problem" :-) Thanks. WL [/QUOTE]
