6 PPC vs. 6 PPC USA

[ehkempf]

I am thinking about having a rifle made in 6 PPC for Groundhog Shoots and actual groundhog hunting. I want it to be a no turn neck .271-.272 and I plan on using Norma 6 PPC brass (I am not into case neck turning or fire forming). My question is if I do this what is the difference dimensionally between a rifle made to these specs vs. the 6 PPC USA. Or better put, can out of the box Norma 6 PPC brass and say Sako 6 PPC USA brass both be used in the same rifle?

Just a note that my Norma PPC brass, with a Knight 66 7 ogive seated averaged .2655. This is based on a sample of 5. Over a sample of 35 cases, the minimum neck thickness was 10.3 thou. There seemed to be one low spot of 10.3 on about half the cases. I didn't keep track of that, however.
