I have 300 pieces of once fired 6br Lapua brass. And, I want to find the most uniform 50 for a competition.
I figured I would go ahead and check volume and see how much variance there is. If they vary a lot as a percentage of case volume, then it may be useful. If they don't vary so much, then it might be worth a quick check just to cull a couple of questionable cases.
I also plan on sorting bullets by bearing surface length and a few other things above and beyond what I would do for a long range hunting load.
Either way... If I've wasted my time, I'll know soon enough.
Thanks!
