I have several carbon fiber barrels and will say they do seem to cool faster. I however do not have any on match rifles. In my limited experience, barrel-for-barrel they do not as well as my heavy steel barrels. I also want the weight in my match rifles. The benefit of stiff-for-the-weight is great for hunting but lost on me, and even a negative for competition. They cost twice as much too. I a not sure what type of matches you are looking at but that's how it stacks up for me.

Let's get the party started:
Highly heat conductive materials transfer temperature more easily than materials with low heat conductivity. Composite made from carbon fiber and epoxy resin is a material with heat conductivity x 40 times less than aluminium and 10 times less than steel. Thus carbon wrapped barrels are insulating the steel core and in return holding higher temperatures longer.

"Our helical wrapping pattern favors the longitudinal thermal diffusivity ( their word, not mine) of the carbon fibres (along the length of the barrel) allowing them to more efficiently disspate heat emenating from the barrel, rather than insulating it.
Because our barrels are engineered for thermal performance, they also move heat very efficiently through the wall (thickness) of the barrel, greatly increasing heat transport and resulting in barrels that cool faster, live longer, and maintain accuracy over longer sessions of fire. "
Taken straight from the homepage of their website.
I seem to remember someone doing a review on the Proof Research carbon wrapped barrels.
Like Ray, he was a doubter.
Same caliber, same length, same profile barrels.
The Proofs ran cooler on the outside surface, in the chamber, and cooled at a faster rate than the steel counterpart.

Hmmm??? "More" efficiently than what . . .. other carbon wrapped barrels or steel?
In terms of thermodynamics, I keep wondering if it's so efficient, where does the heat go? If it's transferring the heat efficiently, the surface of the carbon fiber barrel should heat up fast (an thereby cooling somewhat faster) and feel hot when shooting rather rapidly instead of feeling cooler, huh? Heat sinks work by . . . heating up fast to dissipate that heat over a large surface area for speed of cooling.

Yes, I don't buy into the faster than steel because of the weave pattern lol.. You don't go from a 10x handicap to outperforming just because of the weave.. I am a doubter for sure and I will remain a doubter until I see something other selling points..

I think the only things Carbon fiber barrels are good for is making a light barrel and emptying your wallet. Then again, a #3 chro-moly steel barrel is pretty darned light. So, maybe it's only good for emptying your wallet. 
Next barrel I have on the list is a Bartlein wrapped.
Want something long and fat to meet weight for
Ridgway. Ridgway has you firing 40 rounds and not
alot of time for cool down. Just the amount of time
for target resets. The few guy's I know shooting
carbon are not bitching.....Now what I do know about
carbon fiber is it makes a very nice heat shield for race
pipes on ATV's. It's what I used to replace the aluminum
shields. That aluminum shed heat but held it long term
enough to still burn your leg. The Carbon shield did not
soak it up and kept your leg happy......I think a carbon
barrel could possibly cool faster with the chimney effect.
It's less steel to cool.

There’s a lot less mass to store energy. Faster to heat and faster to cool with less mass.
