If I cared enough I could measure other parameters but weight sorting gets rid of weird cases. After weight sorting I watch which piece of brass produces a flyer and throw it away.
Rather than wait for my brass to fail, I anneal it at a frequency that keeps it from failing. For 308 and a match chamber, that is about once every four firing. That also works out to about once a year given the limited number of matches I shoot. For firebreathing magnums I will do it every firing or every other depending on the brass and rifle. Of course this means that I do not overly resize a piece of brass beyond what is needed for it to fit in the chamber.
Very good advice !!!
The main reason for sorting brass ,(No mater how you do it) is to have more shot to shot
So the more anal/particular you are the more consistant your shots will be.
I have seen changes in things that only improved group size by an average of .005 to .007.
That's not much . but when you add all of the improvements up It can be the difference in a 1/2
MOA and a 1/4 moa group. and at 1000+ yards that can be a lot.
And as BB said one piece of brass is not worth the cost of a good match or a bad shot.
