    I was just wondering what the loaded neck dimesion for the 243 win Lapua brass is with a 105gn A-max seated in it. I want to get a barrel chambered with a no turn neck with .003 tolerence.

    My loaded lapua brass with the 105 gr AMAX measures .272 Great round and Great bullet. I might mention that mine is a 243 Imp. is that makes a difference.

    Just a quick .02 here.
    I don't think I'd have my chamber cut for factory brass. Find out what the minimum amount of neck turning required to clean the necks up is and then chamber for that loaded dimension. It's more work, but more accurate also and you won't have to worry that you'll wind up with a round here and there that won't let the bullet chamber properly because of the close tolerances.
