Gunsmithing Weatherby MKV raceway diameter?

[ugsly]

I have a Short action that was a .308, looking to true it up and do something a little different. I measured the raceway with calipers and getting .7145-.7150. I was going to order some bushings from PTG so I could dial it in off the raceway. Whats any one else coming across for diameters?

Thanks guys,
Casey
