    Finally found some brand new (yes it's out there) 30-30 brass. I know I need to size it, but what about chamfering and deburring the case mouth. I am so excited, never had new, new brass:D;)

    The new case mouths get a light chamfer/debur job. The flash hole is deburred at the same time.

    I think the OP is referring to chamfering and deburring the case mouth. Flash holes and primer pockets are a different issue.

    I also chamfer and deburr new brass and once fired. The factories typically don't do it.

    I do, whether new or once fired, I always run it through the FL die, trim, and then ream and chamfer.

    Neck-size o correct anything thats not already perfectley round.
    Then just barely touch the inside /outside of case neck on reamer
    Flash-holes on everything except Lapua, get spun a few turns

    There is really only two times that I chamfer the case mouths.
    1) New brass.

    2) Trimmed brass.

    So does this apply to ALL new brass or only rifle? I know most say they never trim pistol brass so where does chamfer / deburr fall?

    For pistol, anything w/ a roll crimp. I like the crimps to be uniform. I really should trim brass that needs a taper crimp because it headspaces off the cartridge. But it's worked fine w/out doing it.

    Chamfer, deburr, every reloading, even new brass. Flash hole deburring, i do about every 3-4 reloads, and yes new brass gets flash hole deburred before loaded for first time.

    Since all the new brass that I have gotten needed to be trimmed, yes chamfer and deburr the case mouth. I also neck size only and deburr the flash hole as well.

    Like others, slightly inside and out on the mouth. Run your fingers over a few of your new cases and in short order you'll understand why.

    Does it matter when you chamfer/debur? Like before/after sizing ... before/after tumbling ... ?

    If you chamfer before at least neck-sizing, you'll likely be chamfering an out-of-round case mouth. I don't think it matters in relation to tumbling. Also, depending on the tool used you should deburr after sizing/trimming/chamfering. Most of the deburring tools depend on consistent case length and a round case mouth.

    I treat new brass the same as OF brass. Yes I do a complete going over from sizing, length sizing, and lightly chamfer/deburr as needed. If you do not bother do all that AT LEAST make sure it is not too long and the empty brass will chamber before loading it..
