How Much Runout Is Expected On New Unfired Brass

I have had bad luck with the quality of some of my new brass. It has 10 or more thousandths of runout.

How much do you normally expect from new brass. I want to give the manufacturer some constructive feed back.

    It could be anything in the world until fireformed.
    Once you pull it from a smokey chamber, it'll be right(until you FL size it).

    Well, yes, Mike I know that. But I don't like the idea of all those high runout loads while I am working up loads.

    Len,
    I never reload new brass without putting them trought the sizing die first. That in its self will straighten up some of the run one to where is some what acceptable. If not, you'll just have to fire form them and then work up your load.
    I hope this helps.

    Maybe I'm expecting too much, but I would expect the majority of brass to be .002" TIR or less. The last batch of .300 Win Mag lapua brass ran .0015" TIR for 200 rounds. Only 1 piece was .0025"
