Re: remington 788 23-250 action
* remove the barreled action and inspect the wood stock wherever in contacts the metal. Look for burn marks. If all that looks good, then check the barrel for warpage with a good strait edge (not a yard stick). Check this in at least three places on the barrel. Now run a nice tight patch down the barrel. Feel OK? Did the patch come out kinda sootey looking? If the wood and action look good the rife probably didn't get that hot, but external heat can cause you grief with the barrel.
* now lets say we saw some slight burn marks in the wood where it contacts the action. I'd plan on replacing the barrel, and have the bolt and reciever rockwelled in several places. I doubt it got hot enough to worry, but better safe than sorry. When they check the hardness of the reciever and bolt, you need to be looking for numbers in the 30RC to 40RC area. I don't see a problem with your rifle as the wood wasn't burnt. It'd take about 900 degrees for an hour to give you a problem, but 300 degrees on one side of the barrel will often cause a warp.
