[QUOTE="Pdvdh, post: 1401030, member: 4191"] Just read the SH Thread. Didn't read anything there that undercuts / undermines the content of my Posts above. I did conclude Lowlight is a marketer for Proof. Must be making some money singing their songs. If the CF barrels shoot well, don't shift POI as they heat up any worse than a steel barrel, then those are the reasons to own one, if you're looking for a stiff, rigid barrel to reduce rifle weight. To reduce the weight of a carry/backpacking rifle, for example. That would be the tempting value prompting my purchase. I would not put the CF barrel into repetitive, sustained fire mode, as the steel core is contained in an insulating wrap, which will elevate the bore temp higher than an equivalent contour 100% steel barrel. But I try to avoid sustained repetitive fire with steel barrels also. So no real difference in use for me there. CF appears to cost two or more times more than a steel barrel. Only the buyer user can decide if that's good value for their money. I would never purchase one based on the false advertising claims of cooler temps, which we believe could lead to longer accurate bore life. The thermal conductivity numbers are the best and most appropriate indicator of cooling efficiency, no matter the allegations of thermal diffusivity being bantered about as the more credible intrinsic thermal property of the CF wrap. Ain't so. [/QUOTE]
