[QUOTE="entoptics, post: 1569387, member: 104268"] Awhile back I bought 300 MAI cases (Norma made) for my 300 WM and another 300 for my buddies. After sizing, but before first firing, they averaged 2.602" ± 0.003" That's 0.018" short of SAAMI maximum, and a fairly wide spread. I was initially a little concerned, as the 300 WM myths and legends indicate it has a short neck already, but I had no issues at all with them. I fired them all a couple times, then cut them back to 2.610 (0.010" off SAAMI). IMO, unless your gun is a real bug holer, a couple percent variation in overall neck length doesn't make much difference, and as long as you're aware of the "carbon ring", you can probably run them pretty short without much issue.
