This is one of those questions that cant easily be answered. In my experience, what you're seeing will mean nothing on target. The shooter and the rifle has to be able to shoot the difference to determine anything though. A big ES in velocity will easily swallow variations in bullet weight or bullet jump. So many of these variables are absorbed in the inconsistency of the system(shooter/rifle). Its easy to take them to the range and form a conclusion based on a few groups. Realistically, the shooter's extreme spread will likely outweigh what you're seeing on the scale. Remove bias (blind test), add range(more is better), include velocities, and look for verticle dispersion. Nip it in the bud with a few tests. Most just sort them from the beginning. Probably better to test it. It'll let you know if you need to put in the effort, or forget about it. Most competitors arent concerned with minor but consistent deviations. Its that one round that will cause a true flyer. Like shooting consistent x's, then putting one in the 8 ring at 6 o'clock for no reason. To take value from it though, you have to be able to shoot the difference.
To throw a monkey wrench in things, sort them again by base to ogive length. The theory is that slight variables in ogive arc create variables in seating depth, which results in a variable jump to the lands. Same test method as above.
My guess is you see nothing with either, but dont take my word for it.
On a slightly different note, are these bullets out of boxes of 100, or 500? I seem to recall that sierra advertised at one time that 500 quantity boxes came from one machine, whereas the 100 boxes were a mix of multiple machines. Been a long time, and my recollection could be bad.
appreciated!
