6mm Rem Neck Diameter

[rcw3]

I probably should have put this on the other thread, but I am also interested in what people are finding the loaded neck diameter of the new,unturned) Winchester 6mm Rem brass measures. Are most of them running in the 270" to .271" range, or something different?

My particular bag of brass,7 years old) measured just a tad over .270". I turned them for a clean up cut to .269" for my .271" chamber neck. Others may vary, of course.

It measures about .270 with a berger 115vld. I talked to Dave Kiff last night to order a no turn reamer in 6mmAI and .273 was the dimension he recommended and I went with...I got my brass about a week ago.
