    Do I need to do this to brass that is not trimmed? Thanks.

    In my experience, it depends on the bullet itself and low long it's been since the brass was chamfered.

    On one end of the spectrum, you have brass that was chamfered one firing ago and is mating with a boat-tail bullet. There's pretty much no reason to touch the brass.

    On the other end of the spectrum, you have brass that was chamfered 10 firings ago and is mating with a flat-based bullet. Definitely time to chamfer.

    Then there's the judgment-call area in the middle. :)

    If you're referring to new brass, then you should chamfer before loading. It's also advisable to make sure the mouth is round by passing it partially into a full length die.

    It won't hurt once fired brass that was chamfered when it was loaded to take a light pass with the chamfer tool, just to clean up the mouth. Outside deburring is only necessary if it has been trimmed.

    +1. Other than that, it's only necessary after trimming.

    I do a light pass on all of my brass just for good measure. After trimming, there is no question about it, I ream and chamfer. And so far as how much ream and chamfer is necessary, only enough to remove the lip created by trimming. Don't make it razor sharp on the mouth or it could cause the mouths to split when firing.
