6mm BR reamer specs?

[xs hedspace]

I built this BR rifle, and did a wildcat based on the 220 Swift case, shortened to match the PPC capacity. The rifle gave me groups in the teens, when the wind allowed, but now I'm tired of the case forming hassles, and want to rechamber to a 6 BR. Can I rent a reamer with tight neck, throat for 66-68 gr br bullets, etc? Who rents these, and what should I ask for? Or, can I rechamber to 6PPC, with a 6BR boltface, just move the extractor in. It's a single shot anyway. Help....

Helloooo, anybody out there?? I see reamers for rent, .264, .271 necks, but they don't specify throating. And what about the PPC size base, with a BR bolt head. I don't see a problem, if I can move in the extractor in a few thou, for a single shot????

Nevermind! I measured my fired cases, and only the 6mmBR is large enough, that I only have to face off one thread worth on my barrel, and I can rechamber to 6BR without the hassle of rethreading. And a .270 neck will do, because a loaded BR factory round measures .268" OD neck.
