[QUOTE="rcoody, post: 1287700, member: 91090"] Going back through your post I have some questions What cartridge are you reloading? I am a little confused about your case measurements. 1.6215-1.6225 My calipers only read to thousands. where are you getting the fourth digit. Are you using the hornady headspace gauge for your headspace measurement? Are your reloads difficult to chamber? If not you are bumping the shoulder sufficiently. Is this new brass. Could be the cases are not fully fireformed and that is causing the variation. The ones with the longest headspace are probably the correct ones. you could easily already bumping your shoulder too much. get you some dry neck lube and lube that neck. I see you are using an ultrasonic. I use one too. You must lube the necks not only for sizing but bullet seating too. The benchrest guys like to leave the carbon in the neck for lubrication and consistent neck tension for bullet seating. those super clean necks need lube. So does new brass. you can apply it with a neck brush pretty easily. [IMG]http://accurateshooter.net/pix/caseneck1701.jpg[/IMG] [/QUOTE]
