[QUOTE="djm670, post: 2070923, member: 36341"] Well some body is wrong; not exactly sure who. Have done a fair amount of reading on this subject and while it is true that carbon fibers can conduct an appreciable amount of heat, but to do so the strands have to be perpendicular to the surface that one wants to conduct heat away from. The heat has to propagate down the length of the strand. They can not wrap and or position the carbon fiber stands on a barrel 90 degrees or perpendicular (stand on end like short hairs) to the barrel or chamber of the rifle like they need to conduct heat away from the steel barrel. The only way they can wrap the carbon fibers around a chamber or a barrel is longitudinally and then they encase them in a resin to bind them which further insulates the barrel. So you take a thin barrel which can't absorb much heat without getting extremely hot, and you wrap it in insulating resin and carbon fibers that are wound in the wrong direction for heat transfer. Tell me where that heat goes.. Unless you can ventilate the barrel by passing a cool fluid - air or liquid, there is no way to get the heat out of the thin steel barrel that is incased in the resin and longitudinally wrapped carbon fiber. That they shoot well as many profess, is a credit to the maker of the steel barrel prior to its being wrapped. And the fact that the outer surface of the carbon barrel is always cool to the touch lets you know the heat is not reaching the carbon surface nor radiating from it. [/QUOTE]
