Thanks guys!!!
weight sorting brass will give you brass that weighs the same. it has little to do with the same size cavity inside which is what people are looking for when weight sorting brass. i don't believe the inside cavity size has anything to do with accuracy either but it's a feel good so go ahead and do it if it makes you feel more accurate.
I had about 300 cases and I sorted them into six groups. The two extreme groups of the lightest and heaviest had about 5 or six cases in each and I discarded them. The remaining cases were in four groups of about 70 cases each.
You have to weigh about 50 cases or so to find an average value then decide upon where the groups seem to break and what amount of difference you are willing to tolerate in a group.
Differences in inside cavities give you different pressures, therefore different velocities, therefore vertical dispersion at long range. You say you don't "believe" the inside cavity has anything to do with accuracy... Well, I know it does, but only at long range.
Some like to use a liquid to volume sort and others like to weight sort. I find no advantage in
one over the other. Weight sorting seems to be the easiest and fastest with the same accuracy
so that is what "I" prefer
Most of these responses are unsupported by any scientific means. I weigh virgin brass for competition purposes only. Those are Lapua and Norma cases, and I find very little difference in the weight swings. But the next guy may weigh with water equivalent, and that is his preference.
Much of advanced reloading practices are based on what makes the shooter "feel good". It seems as though everyone in this sport has an opinion, and we are all entitled to that. When a guy can put into print his theory based on actual field experience, I give it serious consideration - but reserve the right to try it and make my own decisions. So no one needs to get their panties turned inside out for any of these issues.
The OP asked about weight sorting for hunting rifles, not competition guns. I think its a waste of time to weight sort hunting brass. If someone else wants to do that - go for it. I don't mind. If you disagree, show me the proof.
