[QUOTE="FearNoWind, post: 953780, member: 50867"] Two "almost" correct answers. Moving air doesn't actually "cool", it simply moves the warmer air away from the heated object and allows more of the object's convected heat to be absorbed by the cooler air (assuming it is actually cooler) as it passes. The larger the surface, the greater the amount of heat transferred to the air. In that manner, "Blowing wind" (moving air) aids in cooling but does not in and of itself cool. It's the ambient air temperature that actually does the cooling. ------------------------------------------------------------------------------------------------------------------------------------ For the OP ..... A barrel warming device isn't something I'd purchase because the barrel's temperature, prior to firing the first shot, is a factor of the ambient air temperature. Any device used to warm the barrel will raise its temperature above ambient air temperature but the relative difference will still be dependent on that factor. A warming device at 20 degrees AT may raise the barrel temp. by (for sake of argument) twenty degrees. So I have a barrel temp. of 40 degrees. If the barrel temp. is 40 degrees the device might raise it to 60 degrees. My barrel will perform differently at 40 than it does at 60 so I don't really gain anything by using a barrel warmer - I still have to know what my cold bore shot is likely to do, regardless of how "cold" the barrel might be.
