Hornady 140 eld match inconsistencies

I received a couple of boxes of 140 grain eld match bullets w/ the box marked .646 g1 bc. I have had great results shooting them in the past by just loading them with a set of plain Jane rcbs dies. I recently purchased a set of Redding match dies and thought I'd take a little more time sorting the bullets. I used both a holland bullet comparator and the hornady comparator to double check when sorting the bullets and the results were slightly annoying more than anything. The max spread out of 100 bullets was .016" from the shortest base to ogive to the longest. I'm thinking either I just have a bad box on my hands or I've been blissfully ignorant in the past and they just shoot extremely well. Has anyone ran into this before? I'm still going to shoot them and I was able to get the ogive .020 off the lands on nearly every bullet. Also, forgive me for the solo cups in the photo, each cup represents a .001" difference than the cup next to it. Also, I did have a few cups with only 3 bullets in it but about half of them had 10+.

Somebody has too much time on their hands. Just shoot the damm things, will never notice anything different.

I don't shoot long-range precision stuff, but at what range does that amount of variance (0.016" or basically 1/64th of an inch) make a noticeable difference?

Fwiw, I am NOT a long-range shooter at all. I have a savage 10fp-le that from a bench will do sub-moa with off-the-shelf federal 180-grain softpoints, and anything better than that is completely wasted in my hands, so I have no firsthand frame of reference for the kind of thing you're describing.

Hornady 140 eld match inconsistencies

I have measured Berger bullets and have found them to be super consistent. I had measured hornady in the past but never kept a record of it so I'm assuming that I switched to Berger because of the inconsistencies. Also, sierra bullets have show to be consistent in my experience.

Basically, here's what I do when working up a new load: I'll do velocity tests up to the max charge (as long as I'm not seeing any over-pressure signs) in 0.3 grain increments, starting at about 2 grains below max. I will do this with a couple different powders and then after I find a 'node' in velocity, I will fine tune the load by adjusting the ogive to the lands length. I start at .005 off the lands and then increase to .035 or so in .005" increments and I can usually get great results though it is time consuming.

I was wondering if anyone else had ran into the same thing using hornady. It's a pain to get the ogive to lands just right if there are .016" differences between 2 bullets from the same box. And while some may think that it's a waste of time, at the end of the day, if I miss a shot, I can't blame my ammo.
