[QUOTE="MontanaRifleman, post: 388452, member: 11717"] It's a valid point and what you are talking about here is transient conduction. The heat energy applied to the bore isn't constant but comes bursts causing a pulse like heating reaction in the wall of the barrel. Once again, I don't think it's significant. The spike in temperature in the bore(throat) surface will cool down relatively quick, IME as the temp stabilizes throughout the wall of the barrel. Once the wall of the barrel becomes isothermic (same temp) we have steady state conduction. In the course of fire, if we allow the barrel to partially cool down to near ambient conditions and fire again we hover and bounce back and forth from transient conduction to steady state conduction. The temperature differences on the inside of the barrel will be more extreme than the outside, and the average temp will always be higher. I don't think it makes a big difference in the rate of cooling between the heavier and lighter barrels. The difference in wall thickness between my Sendero and Finnlight is about .09", .22" vs .31".
