I settled on the 6.5 PCC. It has some support in reamers and dies, but no-one has really pushed it yet. The guys who have not liked it, IMHO were not using the best combinations of powder and bullets. Granted, it is an experiment for me and I might end up coming back to the 6x45. But my calcs tell me I can run the same bullet mass at about 150 faster than the 6x45. We will see if it bears out in reality.

With matches and projects, might not get it done until June or so...the 450 Corvette parts head out to Cerakote next week, then tuning.
