"Indexing" case alignment
For those of us who shoot guns with less-than-perfect alignment of chambers axes to bore axes and bolt faces, and then size them in presses with less-than-perfect alignment from die cavity axes to ram axis and shell holder face:
"Indexing" cases with the head stamp (or other mark made on the case) so that they are placed in the gun and dies in the same orientation every time (within a few degrees of rotation) can make a worthwhile difference in accuracy.
That does not remove the need for making the lengths appropriate, but it may help remove some confusion about die adjustment IF the orientation of the cases changes the measurement any (as postulated in a previous post).
