It was just the end rubber was burned about 20o/o and the stock was melted to a dent the size of a quarter. it lookes like you pushed your thumb down hard on the stock and it stayed it sank in about 3/8ths.
as I said the Honey comb foam rubber never melted in the case. or showed any signes of heat damage.
Under these conditions the action should be fine because the foam will melt below 300o
and that is not enough to change the metallurgy.

As far as twist rate I would chose a 1 in 10 twist so any 30 cal bullet could be used.

I have a 1 in 12 match rifle that shoots great but doesn't like 180 + grain bullets and
will not shoot the 200 or 220 grain at all. (It likes the 168 SMK).

Just my opinion.

That being said, the action is probably OK, but as I said it would still go back to Savage for a better look see. The barrel will be junk from the centeralized heat in the middle of the barrel. (real bad if it's stainless steel). Also it only takes about 700 degrees to start the long term draw back of the heat treat quality (long term). Then if the rifle was hit with anykind of a hard quench (water?) you could well have created cracks in the sharp corners on the action. I just would not chance it, and the look see will be cheap insurance. 4350 Steel is not like hot rolled steel

Think about this; I used to work for a man that had a house fire. In the fire was a Browning Superposed shotgun that came out of Belgum and was one of their hand built guns. He asked me to look at it, and I told Tony it looked to me like the onlything it need was a refinish on the barrels and some new wood. I had him take over to guy that works on nothing but double rifles and shotguns, and is regarded as one of the very best smiths in North America. Eric looked it over, and then said right up front the barrels were junk. The reciever block looked fine to me, but he felt that there was something not right with the way it felt. Turned out that it had warped about .02" (he caught it in the pin holes being missaligned). They packed it up and sent it back to Browning for their opinions (as the insurance company was footing the bill). A year later Tony got a new Superposed identical to otherone (I maybe wrong, but think it has the same S/N). Erick said that if he'd shot that gun, it would have had a massive barrel failure. I never saw the letter Browning sent Tony explaining what they found, but I know they felt it had an unsafe reciever block.

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
