I didn't check neck walls. I did spot check concentricity at the neck, maybe 20% of them. It has been several months, but if memory serves me right, none had more were less than 0.001" of run out. I knew after checking the weight and run out, this was easily the most consistent brass I have used. I don't really need brass of this quality as I typically find Nosler & Hornady brass workable for my needs. I do like high quality though, and I was impressed. When I need brass again, if Alpha makes it in that cartrdge, it is what I will buy.
All measurements were taken right out of the box. No sizing, trimming, flash hole or primer pocket work required.
So you just loaded them as they came, no sizing first? I am thinking to just give a mouth chamfer and fill 'er up.
