Case lengty questions

[roadsterguy]

What means are you trimming your brass, there is a suggested length how much is an acceptable difference? I know there can be feeding issues but assuming you don't have those, consistency would be very important, how much variance is acceptable? Plus what and how are you measuring, and assuming this is all done after sizing.

Sinclare sells a chamber length gage to get true chamber length. .010 less than actual length is generally recommended. For center fire Cases nice for them to be all the same when trimmed but I don't think a couple thousands variation matters much.
