So I just started reloading and over the years I have accumulated an assortment of 9mm pistol brass. I'm looking to achieve an acceptable amount of accuracy out of my load's considering all the brass prep I've done. How would you guy's go about separating this brass that's from all different manufacturers and a wide range of "lots"? I cant see separating my brass by manufacturers, then weight, because I would have a BUNCH of piles a A LOT of load development to do. Would it hurt anything to separate them by weight alone?? What would be the result if I found a good charge weight and loaded up any and all brass with that particular weight? Feel free to chime in, Thanks!
