Can I camfer my case mouths each time I reload?

When case length requires that I trim then I chamfer. I wouldn't say I down load, but I don't run my .17 Remingtons at max velocity either. Better accuracy, case life, barrel life and less copper build up means more to me than another 200 fps.
 
I trim when case length dictates it and only chamfer/debur new cases and after trimming. I don't do it any more often because it is not a favorite activity of mine. I also subscribe to the removing material theory - you are indeed removing material. How much material and the associated effects are debateable, but I guess I would have to see some sort of tangible benefit to make me consider the brass removal and extra work.

And when you find a varmint that can tell me the difference in that extra 200/300fps then what I'm shooting I'll push it up.
