I noticed my Hornady match varied up to 6.5g, Winchester varied 3.2g, and federal varied 2g. Weight was taken after tumbling and cases were still capped. I've only shot the Hornady all the rest are one-shots sitting on the shelf. I wont mix the brands of cases but should I separate cases by weight? How much weight difference should there be? I'm thinking about switching over to the Winchester with it's lower variance. Or am I just being OCD Thanks in advance for any advice for this newbie re-loader.
