Jacket concentricity of .0000″ to .0003″ on target bullets and .0000″ to .0006″ on hunting bullets.
I always adjust my sights slightly so I do not impact my aiming point when shooting groups at 100 yards.Whenever I shoot more than ten rounds and they are say 1/2-3/4 MOA, I’ve noticed the more I shoot at that target the bigger the group becomes. I think it’s because focusing on the hole in the target causes me to allow a little more movement without realizing I’m not completely settled in. I’ve done one thing that at least in my case kind of supports my notion, I’ll shoot multiple groups of ten and then overlay the targets and find the aggregate of these groups tends to stay in a smaller size group.

That is not loaded bullet runout in a cartridge.I know Sierra has pretty tight tolerances with bullet runout.
