I full length re-size, trim to the "trim to length" (max overall case length minus .010"), de-burr the flash holes and champher in/outside neck.
My reasoning is the next time I reload I only neck size. Depending on the load I can usually get away with neck sizing a few times. Once the cases are trimmed to minimum I usually don't have to trim again for several loadings. As far as I know and have seen, once you de-burr the flash holes you never have to do that again. Champhering the necks I do each time I run them through my dies.
I usually only tumble after every 4-5th reloading and I keep a record of how many times each case is shot. Hope this helps. JohnnyK.
