    Has anyone noticed more variation in new brass being fired for the first time? I seem to be having variations in group size and consistency. Just curious if the non fired formed brass may be the cause. Group sized ranges from 0.4 to 1 inch. Cartridge is 204 ruger. I have not checked with concentricity gauge yet, waiting for it to arrive.

    Are you preping the brass before firing the first time??

    If not then I would recomend the following.

    Run the brass through your full length sizing die.

    Trim,chamfer neck inside and out, deburr primer pocket and
    weight sort all cases.

    This should solve the problem.

    It very well could be your new cases. I once had a Rem 700 in 7mm Mag and got new cases and did all the prep work to them. While working up loads I could not get that rifle to shoot under a 1 1/2 inch @ 100 yards no matter what bullet load etc I tried. I was using the new cases every load. Then one day I decided to load up some of the once fired cases with the load that had been the most accurate. I shot three shots @ 100 yards into a bug hole. From then on almost any load and bullet combo in that rifle would shoot under 1 inch all day long as long as the case had been fired at least once and then FL resized. Try some of the cases that you have fired and you may see a great difference.

    Thanks for the insight. I FL sized, trimmed, deburred inside/outside, and neck turned. I have not tried weight sorting. I will also have to reload some of the once fired. Thanks again.

    Don't bother about the weight sorting as it will tell you nothing. There is no way to tell if the weight variations in a given set of cases have any resulting impact on the volumetric capacity of the case. You are pretty much wasting your time on that.

    I have to disagree with Boss on this one!!

    I have been loading ammo for over 50 years and have tried
    almost every thing known to man to try and make my ammo
    more consistent and weight sorting has been one of the things
    that has helped to lower the standard deviations(Very important
    for long range shooting)Reducing the amount of vertical stringing.

    Also if weight sorting is not important then how can Nozler and other
    premium brass makers charge over twice the cost of non weight
    sorted brass and sell all they can make.

    Volume has a large influence on burn rates of a given powder charge
    and weight sorting is the simplest and fastest way to get the volume
    of your cases consistant.

    But if you are satisfied with 1 to 1 1/2 MOA then it may not be worth
    the effort ,But I like to squeeze ever .001" out of my loads .

    Nothing personal Boss just my opinion

    Nosler doesn't make any brass... they just sort it and prep it. The brass is not only sorted by weight, but also chamfered (inside & out), pockets are uniformed, flash holes de-burred, and are ready to load right out of the box. I'm thinking all that contributes to the increased cost... not just the weight sorting. ~yb

    Understand and I would do it but it made no difference---my Smith who is a HOF shooter (held world records) as well did very extensive testing to determine if it made any difference and found that it made no difference at all.

    i'm with Boss on this one. i only did a little testing, but it was enough to convince me that weighing cases gives you the weight of each case. it doesn't do much to segregate cases that have the same "interior volume".

    Reading this thread got me thinking. Sorry to resurect an old thread, but:

    I wonder if sorting by weight can help tell us about "bad lots" or poor quality control. Now, a lot a brass that has great variation in the weight might also have variation elsewhere.

    Could it be that this is the reason a lot of people swear by weighing their brass? Because it has helped them avoid bad brass?

    I am debating about getting a digital scale for weghing my brass. Hmmmm
