Come on Cam😆 Less metal quicker to cool. The wrap is also a great insulator.
Abe got mine done done, you would have to ask him.

Carbon barrels look cool to

That's why we insulate houses & hot water cylinders etc to keep the heat in & cold out.

The carbon barrel on my CA 10 is cool to touch but the metal end cap certainly isn't.

Same experience with my carbon one, cold on outside and hot as shit inside.
Found it was actually hard to gauge how hot it was,
And took a long time to cool.
Probably not an issue on a hunting gun.

Was the barrel accurate ?

Yes for a 308 it was.

Interesting article here about carbon-fibre wrapped barrels and cooling. Carbon's Next Step Looks like you have to use the right sort of carbon fibre.

Yes as I thought. .. I asked the question because I can hold a white hot 8mm carbon rod about a inch from the hot bit and its cold.

Rebranded to Bla$er....fixed it....

All I know is that with a laser thermometer my current barrel cools shitloads faster than it did in the same profile barrel unwrapped.
Shoots my zero, hot or cold and I have shot 2 10 round strings with projectiles I wanted rid of, and both strings with a slight vertical component, went under 1.2" @ 100 yrds.
Try that with a standard hunting contour barrel.
My original point being, not only are they lighter, they maintain accuracy and cool way faster. More than you need for a hunting rifle..
Fluting is old school.

I shoot heaps without cooling with standard hunting barrels & have never actually found them to string or open up when hot, submoa from the finnlight for a 5 round group after firing 15 in a row etc

Intersting Dave.. where are you measuring temperature at?
Logically it should get hotter quicker as there is less mass to heat and it is insulated.
I dont doubt that it would/should be more stable and lighter than a standard barrel.
I only shoot 10 shot groups with the 303 as its the only thing I have now with a 10 shot mag and a cant say I have noticed its groups open up either

I forgot to say velocities were within 20 fps. You may not see any stringing at 100 but velocities will vary markedly effecting Medium/LR shooting.


Doesn't fucking matter in a hunting rifle as that is what mine is. But wrapping pisses over a none wrapped barrel if accurate and done properly, in all facets imo.

No actual knowledge but to me it seems likely that the interior metal remaining probably gets hotter... (same energy, less metal) but the carbon that insulates doesn't and is stable in spite of the heat which adds consistency to the barrel flex over a conventional for the same amount of shooting... accuracy claims make sense?

For the metal to be cooler, the carbon would have to dissipate heat better and it don't do that...

If the heat isn't being dissipated, the barrel being insulated by the carbon and running hotter, I have a hard job believing in extended barrel life with carbon wrapping..?

It would be interesting to shoot 5-10 rounds down a Carbon barrel, followed by a conventional barrel with the same ammo & time then stick a thermocouple down the bore & see which was hotter, out side barrel temp means bugger all.

A suppressor with a decent cover on won't radiate bugger all heat creating mirage compared to a non covered one but touch the end of it after a decent string of shots 10-15 mins after & you will know about it....
