I think the metal that touches the bedding would be the primary source of the heat.

Not sure how you would ever get an action that hot, maybe full auto M14s? You have to get an action pretty hot to break down the epoxy and remove a glue in. The heated epoxy takes on a granular look at that point. I have never seen that in a bedded rifle, even the ones from Florida where internal temps in a car can get up to 140 degrees in summer.

He didn't tell me anything, that I remember, about actual action temps, he just said that epoxy with metal in it was a better heat sink than epoxy without metal.
I assumed he had done some sort of testing to determine that.

One other thing to consider when dealing with a fiberglass stock is that most of them are made with a polyester resin, a lot of it, its throughout the whole stock. Its shrinks. Enough that if one side of the stock has more resin than the other side the stock will warp as it cures. Its also shrinking over time. We bed a stock with extremely thin layers of epoxy and worry about how it will shrink over time. What about the 8"x1" worth of resin under the entire action? A little heat on one side of the stock will also make it grow. You can visibly see the barrel shift off center in the end of the barrel channel if you let the rifle sit with the sun baking on only one side of it. All of the stuff we are working with moves. I can measure the tightness of a bedding job change from freezing temps to summer temps. Not because the bedding is moving, the whole stock is moving. Despite all of this a good bedding job shoots surprisingly well. I still like glue ins though, because of what I just said.

Maybe hes talking about the action being a heat sink. As epoxy cures it produces heat and needs heat to cure. If your action is cold it doesnt cure the epoxy correctly. I heat actions as they cure so they dont just sink that heat away.

Just an update got the pro bed in mail but have a shoot Im going to this coming weekend so will not start on it till after that. I went with the pro bed because I think it will be easier to use and really no other reason. Probally any of the ones mentioned would work if I knew what I was doing lol...
Will try and get some pics of it when I get started.
