Just some info about brass concentricity/ thickness variance around the case. Using my NECO Concentricity gauge I measured 50 .308 cases of Federal GM, Lapua, Lake City 79 Match, Nosler and Winchester. The following post indicates the extreme variance and standard variance in brass thickness uniformity. The Gem dial indicator can only measure well to .0005".
Nosler E=.0015", S=.001"
Winchester - E=.0035", S=.002"
Lapua E=.0045", S=.0035"
Federal E=.006", S=.004"
LC E=.007", S=.0045"
I highly recommend that everyone with the means to check brass do so, there is a lot of hype on the internet. Of course my results only reflect data determined from my 50 cases (each brand) and may not be what you find with your brass.
I just recently checked my Nosler 338 Win Mag brass and all were within .6 grain of the average weight and all were within .0015" in brass thickness uniformity around the case. The Nosler brass does appear to be very fine brass, how long it lasts depends on how it is used/abused on the range and reloading bench.
