[QUOTE="Gamesniper19, post: 1589007, member: 95013"] You are hitting on some pretty solid points. The data I am about to share has to be shared with some generalities to protect IP. I personally asked some of the exact questions of CF scientists who sit around all day making carbon fibers and developing resin compounds. I have been in the shop and seen it done. Their words "If you have a carbon barrel, made of 100% solid carbon and no resin and compared it to a 100% solid steel barrel of the same contour - heat transfer would be similar" I have seen the testing - conducted by the military so there is some unbiased data to support the premise that military steel barrels are bought for 125 bucks and carbon barrels are bought for 2x or 3x barrel over barrel, so they better give better performance and life span by atleast >3x to justify. In that test, the temp of a steel barrel and a CF barrel are nearly exact seconds after the shot. As time progresses post shot is where the difference starts. The CF barrel core is statistically significantly cooler over time - meaning the carbon is moving the heat away from barrel faster. Also, the outside temp of the CF barrel was hotter - so when you touch it "feels" like it is hotter than steel when in fact, that is what you want. side effect - more mirage, especially during long strings of fire Secondly - under that same test, firing a bullet every 10 seconds for 20 rounds, the core of the proof CF barrel was statistically significantly cooler than the steel barrel of the same contour after the first shot. The outside temps again were hotter with CF barrel - moving heat faster. Not all CF barrels are the same. CF is not the same, resin is not the same, wrapping patters are not the same. So, not all CF barrels have the same results. The proof cocktail does NOT insulate the barrel. It moves heat faster than steel I dont work for Proof so I have no vested interest in anyone going out and buying one. In fact, I buy other barrels too. I do have a vested interest in data and understanding exactly what is going on with what I do buy - so sharing what I learned is why I am here - knowledge is power and sharing that knowledge is valuable.
