I have the Trim-pro 2 powered trimmer and the three way cutter. I tried setting it up to do my .308 cases but I never could get the chamfer to cut evenly around the case, inside or out. I got frustrated and put it up, went back to just trimming them with the TrimPro and doing the rest in separate steps. I can't say 100% that it was the fault of the tool and not the way I set it up, but I got tired of messing with it. And I'm generally very patient with stuff like that. It would've been ok for bulk plinking ammo, but my results were not as good as I can do by hand.
Sorry for the late reply, but I think you made the right choice for your purposes anyway.
