Dang, I wish I would've known that before I had my custom reamer made. I've only got two dimensions on that whole page that differ. Neck dia and a little less fb.
Looks like some very good data. Just in case someone is interested:
ADG SD: 0.3513
Lapua SD: 0.3504
Can't comment on the brass quality but the data generated indicates good data generation technique .
