[QUOTE="J E Custom, post: 1166349, member: 2736"] I weight sort all rifle brass and feel it is worth the effort because when I first started to do this , I was trying to figure what was causing the occasional flyer. I came up with many reasons and set out to eliminate all of them if I could. case volume was just one of the reasons. Neck tension, case OAL length differences, work hardened brass (To many shots before I annealed them), Improper sizing (Not consistent), not loaded concentric (Bullet and cases had to much run out), Differences in case wall thicknesses, Bullet weight differences, Bullet diameter differences, ETC. I then set out to see what was the best method to test/compare volume. I tried using ball powder, de mineralized water with a wetting agent and these methods proved to me that the brass has to be prepared as identical on the outside as possible to be consistent. some cases had different depths of extractor groves and different case head thicknesses. (This is the reason I feel that brass should be kept in batches/lot numbers even if you don't weight sort). When I prepped brass from a single lot I found poor quality control in some brands as stated earlier and no longer buy those brands if I can avoid them. The reason that I weight sort is because it is as accurate as the other methods but is much faster and produces the same results. Note: In my opinion if everything else is not done to get the best consistence weight sorting or volume testing is a waste of time. In many cases loading random/mixed cases produced good results, but when all the steps mentioned were used accuracy was improved, some times by very little but in some, it was improved drastically. If you do all of these things It will not guarantee sub 1/4 or even a 1/2 moa but it will improve the accuracy to some degree in my opinion J E CUSTOM [/QUOTE]
