I would stop there and go hunting with it. I would at some point just make a major change with different powder or bullet or both as it looks like something is a mis match with that load. If they are older Nosler's at one point they would mix different runs of bullets in the same box. You may have some from two different sets of dies. If this is the case there might be enough difference in weight or dimensions to measure and sort the bullets into two or more batches.

I would also check the case necks for uniformity and cull any that are off very much in thickness.

"When you disarm the people, you commence to offend them and show that you distrust them either through cowardice or lack of confidence, and both of these opinions generate hatred." Niccolo Machiavelli
