[QUOTE="Pdvdh, post: 2071673, member: 4191"] It will never be put to rest by any attempted efforts to answer your question. All you need to know to determine which material transfers heat faster, is the thermal conductivity of the steel in a barrel, versus the thermal conductivity of the CFW media. The higher the thermal conductivity coefficient, the faster heat is transfered thru the media by conduction. When a Christensen Arms' engineer provided the thermal conductivity for their CFW to one of our Forum members, it was about 1/4 that of gun barrel steel. Good luck trying to get a thermal conductivity value from the barrel manufacturers... I suspect that Christensen Arms engineer is no longer employed. The brighter side of the issue is, the lower heat transfer rate thru the CFW isn't a non-starter or deal breaker, given reasonable rates of fire used by most knowledgeable LRHs. Guys that understand rapid rates of fire from fire-breathing dragons shorten throat and barrel life. I'm well schooled in heat transfer. I understand CFW barrels transfer heat less efficiently than steel barrels. I now own 3 CFW barrels. I don't worry about it for my application and use. [/QUOTE]
