My question specifically is to #4 on this post.

I'm weighing some new Nosler 7-08 Brass (first time I've attempted to sort brass this way).
All the new cases have a neck thickness of .002-.003 (90% are .002).
Weighing the first few they come in at 169 grains. So when weighing and separating according to the above criteria in #4....

WHAT SORTING PILES DO I PUT THEM INTO ACCORDING TO WEIGHT?
Is the normal variance 10%? 5%? 2grams, 2 grains??

Just trying to learn at this point, loading for a single shot Luxus (NOT a target gun) but I want to learn, and I just got the Forster case measurer tool that measures run out and neck thickness.

Thanks!


I'm a bit concerned about this. If that many of your cases have neck thickness variation in excess of .001" then that's a crap lot.
