[QUOTE="Mram10us, post: 2071646, member: 111667"] I would disagree that you can make a fluted barrel the same weight as a cf barrel. The minimum wall thickness is generally .150 per side across the barrel industry. That means the flutes can only go that deep. That is extra steel that is not there when turned down for CF. The CTE is still interesting to me. It shows CF is lower on the scale, however, the Specific Heat has to come into this too, doesn't it? No expert, but I know the amount of energy needed to heat a pencil barrel v heavy barrel is much less. The CF (with associated resin) have much different Specific Heat than the steel. Here are some numbers to play with. CF barrel steel volume = ~10in^3 Steel barrel (Remington Varmint contour) volume= ~20in^3 Obviously, twice the volume of steel to heat and cool without taking into account the CF CTE. Curious what the numbers show for time of heat dissipation.... edit- numbers were off [/QUOTE]
