Got it. I see the 7mm Grail on his reamer list, and will be contacting him for more info. Thank you!
Looks like an A.I. only holds about 5% more powder (see 25-06 vs 25-06 A.I. posts)
I'll check it out. I don't have a long action with a .473 bolt face right now though. Just the .532 bolt face and two short actions with .473's. One is a .308 and one is a 6mm284.
Sounds really cool though.
