Carbon barrels

I lost the will after the 1st all-steel barrel deflection test:
If you do go for a carbon barrel don't forget to text your quarry prior to each shot so its fully up to speed in the detail of it's pending demise.

Carbon wrapped..
Thin barrel wrapped in carbon. Makes them very stout and light, but fatter. Heat dispersion also beneficial.
Wouldn’t bother personally, prefer a classy blacked rifle in walnut. But to those wanting a 18” in a pse stock job and a big aics mag with a scope able to dial to 45,000 miles, it’s a good match
Wouldn’t blame anyone for buying them,

Yeah, but you’re not ‘cool’ anymore! How are you going to impress your friends at the stalking show

That's true. Always been on the **** end of the cool wall me.Yeah, but you’re not ‘cool’ anymore! How are you going to impress your friends at the stalking show
Is that like tacticool gear?
Can't beat the laws of thermodynamics. A barrel can't heat up slowly and dissipate heat quickly at the same time. A carbon barrel either heats up quickly but dissipates it quickly, or heats up slowly but stays hot for longer. Not sure which one they use in their marketing. For sure though, it could be made to be more rigid/stiff for the same weight vs. a steel barrel.

A friend of mine said to me he regrets having a carbon barrel on one of his rifles as he occasionally does some plinking at steel and it cooks the steel barrel and is a bugger to get cool. I’ve no experience of them so can’t comment but interesting comment you make in light of my friend’s experience. I personally wouldn’t entertain one but that’s just me. My Sako 75 Finnlight with carbon stock is uber light and I wouldn’t want to go any lighter.
Eh?!
Let me run a bead of weld along a bit of cold metal. Should take me 5 seconds or so. In the interests of proving your laws of thermodynamics, you'll be ok to pick it up in another 5 seconds? Fast to heat up so must be fast to cool down, right?!
From what I’ve gathered and advice taken is they’re not ideal for range use - I was led to believe the carbon wrap acts as a insulator and slows the cooling of the steel inner which has led to some problems in the past. However not all carbon barrels are equal either. Could be the case of all being tarred with the same brush.
This is an interesting watch:
That example isn't really the comparison that I'm making though. The rate of heat transfer from welding into the steel is significantly greater than the rate of heat transfer from the steel into the surrounding air as it cools down. So no, the time it takes to cool down will be much longer.Eh?!

To make a fair comparison example, run a 6" weld at 180 amps on 5mm plate (lightweight barrel) and 15mm plate (heavy weight barrel). 180A on both because the heat energy input has to be equal (same number of shots).
The 5mm plate will be hotter than the 15mm plate, but it has a smaller thermal mass so will initially cool at a faster rate than the 15mm plate. There is a crossing point where the 5mm plate will become cooler than the 15mm plate, even though the 15mm plate starts at a lower temperature. Both will reach ambient temperature at roughly the same point.
What that means, is that unless you are doing very long shot strings, a heavy barrel will heat up less and therefore have a lower risk of POI shift.
Multi material barrels like carbon wrapped ones require a bit more thinking
Thin barrels are always a trade off but often very acceptable in normal shooting scenarios.
OK, I think I misunderstood your point.

I have one in 6.5 PRC. Love it.
I was fortunate enough at the time I bought the rifle that, had i wanted to, I could have purchased a more premium rifle. I chose not to; and don't regret that decision. Instead I spent the money on several nice stalking trips.
The trigger is excellent and the barrels work faultlessly. Mine is punching clover leaf groups at 100m - which is plenty good enough for me!
Anecdotally (as I have no actual metrics or evidence), the wrapped barrel seems to retain accuracy better over a rapid succession 3 - 5 shot string than fluted steel barrels.
