At the SHOT show I saw where Forster is now making a cutter that trims, and chamfers the case mouth inside and out at the same time! The downside with it is that it is caliber specific, so you can't just buy one to do everything. I think they have brought it out in .22, .243, and .308 only so far.
I like the Forster set-up for cutting out the crimp on the primer pocket of military brass. I think removing it by cutting it away works better than trying to swage it.
