Do any of you guys rebate rims to work with the ppc boltface? What is the best way to go about it? I have a big lathe and seems like a lot of work to indicate in every single piece of brass to turn rims.

Good idea.... I'll dig into it a little more. Thanks Gabe
I shoot my 30BR on a PPC boltface drop port Viper. I ground a HSS tool that is the width of the extractor groove of the 30BR case. I use this to make 3 progressively "deeper" cuts of the rim moving towards the chuck to keep the case stuck into the Wilson trimmer case holder [ deeper means towards the center ]. The 3rd cut gets me to the correct dia. After the 3 cuts I plunge the extractor groove to the correct depth by going to the number on the dial I determined previously.
So, I go cut - dial, cut -dial , cut, forward to extractor groove, tap the case with a small hammer to make sure it's still tight into the case holder, then plunge to number. You want to barely touch the front face of the rim. I then take a small, fine metal file and put a tiny radius on the back outer edge of the rim to help the extractor and also a tiny tiny touch on the front edge of the rim to make sure there are no burrs.
I have a 1/4" or so brass rod centered by the spider and spanning the chuck spindle and in the mouth of the case that I use to knock the case out of the holder.
It seems to me that the one pass custom made cutter I have seen pics of would have a tendency to push the case out of the holder but they obviously work.
Note, I don't touch the large bevel just in front of the extractor groove.
