[QUOTE="Litehiker, post: 2573018, member: 54178"] There are many types of carbon fiber encased barrels. Most have the CF wrapped directly on a barrel that's been turned down to a skinny profile. Some "separation' problems where the CF comes away from contact with the barrel have happened with this type. There are several ways barrels are wrapped in CF (overlapping helical strands as PROOF Research does), or CF layered in various axis of CF fabric and/or tape or merely a CF fabric wrapping . Of these I like the PROOF barrels best for the uniformity of layering CF strands and the longitudinal strength of that "Maypole" wrapping. I have SWIX cross country CF racing ski poles with "Maypole" style wrapping and they are [I]extremely[/I] stiff as well as light. Also the various types of proprietary resins used make a difference in the CF wrap performance and longevity. "Buyer beware" is my advice when choosing a CF encased barrel. Do your homework as CF encased barrels are FAR from equal. But a few CF wraps actually do [I]not[/I] touch the barrel but are sleeved and touch the receiver and/or a small area at the rear of the chamber area and then again at the muzzle where they are capped by a threaded nut that literally stretches them, making the CF casing a [I]tensioned [/I]casing. Weatherby uses this latter system and it works very well. Personally if I were to get a CF encased barrel I would opt for this type to avoid possible delaminations and to cool the barrel better. In fact I feel those Weatherby rifles with titanium actions, CF stocks and CF tensioned barrels are about the most technically advanced hunting rifles on the planet. Meanwhile I'm happy with my 6.5 PRC Browning X-Bolt Pro with its CF stock and stainless barreled action. Eric B. [/QUOTE]
