Re: Ideal Barrel for the .308..?
KC, sounds to me like you dodged a bullet. As JE said, if the foam never got hot enough to melt, no metallurgical change occurred to the receiver or bolt, As Gary said though, the barrel could have warped, even without any metallurgical damage, but you're going to change it anyway.
A suggestion: While you're waiting for a barrel, contact (Remington, or Savage?) and see if they will inspect/test it for you. No harm trying. If they won't do anything, you can do a dye penetrant test on the stripped receiver and bolt to look for cracks. Unless you are experienced with dye penetrant testing, you will need a technician who is, because of all the crevices, corners, pockets, holes, threads, etc. It will be hard to get the dye out of them without overwashing and maybe missing a real crack with the developer.
As far as softening or hardening the receiver or bolt, neither would occur at temperatures below the melting point of the foam.
On barrel twist, I would go with a 1 in 10.
Good luck, Tom
