Like Dennis describes, I've found the Lapua 308 Palma brass quite consistent. Weight sorted 300 yesterday. High was 174.6 and the low was 173.1. Of the 300, 50 were between 174.1 and 174.4, 225 between 173.4 and 174.0 and 24 between 173.1 and 173.3. In my experience , Lapua brass has shown very consistent weights in the following calibers (in this order)
308 Win Palma
6mmBR
6.5x47L
Followed by 308 Win (LR) and lastly
223Rem.
This is all of the calibers Ive personally weight sorted.
To be honest, Ive tested whether sorting by weight matters (for example shooting lightest bullets in heaviest cases vs. heaviest bullets in heaviest cases vs lightest bullest in lightest cases, etc) and it has mattered at 1000 yds (a little), but barely enough considering other factors. It took weighing powder to 0.010 gn, annealing every firing, dedication to very consistent neck tension and tipping bullets plus a very accurate rifle to even see the difference (which again was very slight). I still weight sort brass, but mostly because its a one time process rather than I feel its imperative for consistant accuracy.
