[QUOTE="Buano, post: 434072, member: 21641"] JE, You aren't following the engineering. A carbon wrapped barrel dissipates heat faster than a solid steel barrel, A carbon wrapped barrel is stiffer than a solid steel barrel, and, A carbon wrapped barrel is lighter than a steel barrel. Since the carbon wrapped barrel is stiffer than a solid steel barrel, barrel harmonics are minimized relative a steel barrel, meaning more loads will shoot well and most loads will shoot better than with a steel barrel. This is the ONLY process shown where lighter (almost always) means better accuracy. Your claim that, "The most accurate barrel is a perfictly true contour or strait cylinder that is dimensionally identical in thickness at any point from the bore." is wrong. There is no engineering principles to support such a claim. • The most accurate barrel [B]for a given weight[/B] would have a relatively thin barrel with large reinforcements on 3 sides to get maximum stiffness for a given weight. Since this is impractical to manufacture & would be EXTREMELY expensive to machine, I never expect to see such a rifle. (This would have immense surface area to radiate heat.) •The most practical version of this would have a barrel that is thicker in its middle to add stiffness, thicker near the chamber to control the explosion, and tapered towards the muzzle where added material would not appreciable help with stiffness. In practical shape this would mean a bull barrel with taper towards the muzzle. Although this is correct from an engineering standpoint, such a barrel is ugly. Since buyers don't buy ugly guns I don't expect to see many of these. • The most accurate barrel would be drilled into a massive steel billet with 20 or 30 tons of mass to absorb heat and resist flexing as a load is fired and would have water lines running through it to carry away excess heat. As this is absurd, the bull-barrel is the closest most of us will come to seeing such a weapon. • Carbon wrapping adds the stiffness and heat dissipation of the gusseted barrel without metal ribs protruding on 3 sides and does so in a light-weight form. Your statement that, "On the larger bore rifles heat is a problem because it (presumably referring to carbon fiber) acts like an insulator and feels cool on the outside but can be over heated on the inside to the point of ruining a good barrel from overheating the bore." is simply WRONG. Carbon fiber conducts heat away from the hot center of a barrel [B]faster than stee[/B]l. (Steel is not a very good conductor of heat & [U]many[/U] things conduct it faster.) There is a valid reason carbon fiber barrels are rarely seen on guns with immense recoil. That reason is inertia. A heavy barrel simply kicks less fast upon pulling the trigger so felt recoil is less. For this reason few .378 Weatherby or .500 BMG rifles will be produced by Christenson Arms. (Any sane person would want a .50 BMG to weigh [U]at least[/U] 25 pounds.) [/QUOTE]
