I admit to trying this only once with a fine ball powder as recommended by Jerry Theo. I've searched on the net on this quite a bit, but got to wondering (again as I do from time to time) If ES is as low as you are happy with (and I acknowledge that this smacks of accepting mediocrity), is anything to be gained by measuring capacity? In other words does variance matter to accuracy in any respect other than muzzle velocity? I ask as I did a very small sample test of our locally made brass, with thicker necks and although the variation is more than my sorted and "touch turned" WW, I nevertheless achieved great ES numbers so far (over 4 loads). I'm wondering whether I'd be any worse off with this brass if I turned the necks a touch to even them out, when compared to my sorted WW. I'm thinking probably not, but I would need to see how runout progressed with cases that have potentially thinner and thicker sides in the body... Thanks for any thoughts on this. Speculation is welcome too!
