All the 6 Br Lapua brass that I have dealt with this year is running between .012 to .0125 neck thickness.

Interesting. I haven't bought 6BR brass for a year or two, but it all measured .0145 to .015 neck thickness (over 3 or 4 different lot numbers.)

If they're shipping at 12.5 thou now, I wouldn't have to turn it.
