[QUOTE="bluedog69, post: 3055633, member: 118823"] Probably nothing wrong. You do have to spin the case until you get the shortest measurement to make sure the case is in perfect alignment. Just like measuring COAL you spin the shell until you know the base is flush with the tool. If it is a little crooked it will measure longer. If you want to go to a whole other level some guys take out the ejector spring and pin and seat bullets into the lands to make sure the brass is being pushed back against the bolt face as it is fire formed the first shot. This minimizes case stretch in the base area and lengthens case life. No case head separation down the road. You do need to fire form it and may have to fire it twice without any shoulder bump at all to get them stretched to where they are tight and don’t want to go back in the gun after being reloaded. A tight tight shell is what you want to get your measurement off of. Then figure out where .0015 or .002 is at when you resize. [/QUOTE]
