[QUOTE="TRexF16, post: 2560322, member: 108912"] Duckman, I only have one AI (.35 Whelen AI) and I use the COW method and factory .35 Whelen Brass. Couple thoughts: Since you are planning to neck down Lapua 30-06, you will have no headspace issues regardless of how your chamber was cut. You'll be able to neck down for a crush fit. I haven't used Lapua 30-06 but my Lapua .308 brass runs definitely towards the thick side in the case necks (.015"). If their 30-06 brass is similar, you might end up needing to neck turn or ream for it to safely fit your chamber when a bullet is seated. If it were my rifle, that would really lead me towards using the COW method for the initial fire form - you'll have no worries with the fit of the bullet and case neck in your chamber for that initial forming. Once your cases have the shoulder nicely blown out, THEN you can check the resultant case neck dimensions against your chamber and do any turning that might be needed. I don't think anybody mentioned that aspect of your decision yet in this thread but might have missed it. Good luck with it, Rex [/QUOTE]
