[QUOTE="nheninge, post: 277918, member: 13085"] Yes, I think fire forming followed by FL resizing should reset this difference because your dies body/shoulder/neck are drilled/honed with concentric bits and should have a single axis if they are quality dies. However, thick/thin sides run the length of the case. This is only noticed if ID measurements of variance are taken. I find a lot of value in culling cases with increased neck variance. If I get 200 good cases with no variance (followed by neck turning), those 200 cases may last the life of the barrel if the brass is treated properly. A lot of concentricity/runout problems are avoided since I never start with a problem. [/QUOTE]
