[QUOTE="swampratt, post: 2840057, member: 15054"] I tried just neck sizing..The brass will grow longer in the shoulder each time you fire it when neck sizing until you get a stiff bolt ..at this point it will grow very little in the shoulder datum point. after 6 or so reloads No more growth there but the case neck length will grow at about .0005" per firing. This is what i got in my .308 when Testing.. The neck sized rounds were less accurate than FLS rounds. BUT my FLS die has been honed and polished to minimally resize the case.. no more than .001" resized anywhere on the case. .0005" or less in most spots. I measure shoulder set back after FLS and keep that to .001" or less I prefer less. To find lands I do like Jcann . I seat a bullet in a case with minimal neck tension..This bullet is colored with a sharpie. I chamber it and remove and look for witness marks.. keep seating deeper until no marks are present.. That will be totally off the lands. Some bullets like to jump .040" or more and some like to be jammed .. Test Test Test. Some guns do not play by the rules. Enjoy the shooting. [/QUOTE]
