[QUOTE="winmag, post: 368686, member: 22166"] It almost feels like its pushing hard on the bolt face. Could I have somehow messed up the bottom of the brass while de-capping? I do plan on getting a measuring tool that measures at the ''O-give'' right after I get a case trimmer. The calipers just dont cut it I guess. Still confused as to why if I backed off from.015 and an extra .005 I still had trouble.You wouldnt think the bullets would have .020 difference even measuring c.o.l. with calipers. I have 25 rounds loaded in groups of 5 starting at 56.5 grains of IMR-4831. for the first 5. then 57.5 gr on the next 5 and so on in 1 grain incriments on groups of 5 to 60.5gr on my last group.( .4 grains under book max),depending how the lightest 5 bullets shoot(pressure signs not accuracy) it may be a short day. If the bolt closes too hard on any, Ill probably just pass them up for safety reasons. [/QUOTE]
