Bar-sto barrels states that 500F doesn't affect short term wear on a barrel and does not affect the heat treatment. They have more experience than I do and I am not familiar with the alloy to know what the annealing temperature is but I would never let a barrel get hot enough to discolor - which is what happens at 500F. Firing a bullet through a barrel that is that hot cannot be good for it due to the friction of the bullet. Now there are two issues with that much heat. The barrel will expand so the bore will increase in size, a little. The bullet jacket is a self lubricating metal but it looses some of that quality with heat. I doubt the two cancel each other out. In some rapid fire competitions a pistol barrel can get hot enough to discolor so it might be that pistol barrels erode less because of the straight chamber and bore. I don't think I am going to punish one of my guns to see what the effects are in the long term.
Keep 'em cool and keep 'em shooting straight.
