Had this one come in that was in a house fire. It didn't get hot enough to affect the hardness, but the smoke/water/heat combo did a number on the metal. Refinished in Cerakote Midnight blue. Replaced most of the springs, since they were beyond salvage, and heat really does a number on springs. The soot wouldn't come off of the stocks, so a sand and hand rubbed oil finish did the trick. She's back ready to work again.

If it was in the heat of the fire I wouldn't fire that weapon.

The general rule of thumb is that if the oil soaked wood didn't actually catch fire, and the springs did not get hot enough to take a set (lose their springiness), then it didn't get hot enough to crystalize the steel. Neither of these signs were present in these guns, which were in a basement gun room that was underneath a first floor fire. This damage is more indicative of acid/smoke/water damage vs. actual fire damage. The pine walls in this gun room didn't catch fire, so there isn't much worry about the structural strength of the chambers. Deep pitting would cause concern also, but that wasn't the case on these guns. This one is one of the last of about 30 from this fire that have been completed with no issues. Many of them were store loaded, and none of the ammo cooked off, nor did the shot shells melt or deform. YMMV.

Yeah if the ammo didn't cook off you should be Ok but I've cooked a 60 so that shouldn't be the measure of abuse. Looks good btw.
