Why use a carbon wrapped barel?

[MostlyUselessLurker]

Wouldn't it make more sense to ask Bartlein, Proof, CarbonSIX, etc. to prove their claims if it matters? That is the only place you will find the proprietary information that could prove these claims to be true or false? (Disclaimer: I know companies will not divulge that information to anyone.)

Until that information is available to someone willing to verify, the conversation is just as meaningful as "which came first, the chicken or the egg?"

This thread has turned out to be quite entertaining.

from just a normal old person with absolutely no background to offer any dog in the fight:

this is what it sounds like -

on one side of the argument, the guys that believe carbon fiber barrels cool faster Yell and scream —— that they "just do!!!" No need to show any proof.

then on the flip side The guys that believe all steel barrels cool faster say "they just do and I don't have time to prove it"


from a simple minded fella, it sure sounds like everybody just has their own opinion - and that's how it falls.

god bless America!

OK. If you say so.

I'm a so-called engineer. But I owe you nothing. I don't wanna state my opinion with numbers you desire. Never gonna do it without engineering pay. Anyhow, I'm just a a so-called engineer. What could I offer of any real value?

The most pertinent material property (coefficient) has been identified for your use and understanding. Still not sufficient for your personal needs.

Maybe research locating, contacting, and badgering one of your REALLY GOOD "so-called" heat transfer engineer friends.

Its not about oweing me, its about backing your claims about cf. i can see this is going nowhere with you, so God bless you and hope you had a good christmas.

I do see your confusion. I've tried to help you with it. I brought up the topic of thermal capacity many, many posts ago. Thermal capacity is a property of both the material itself and the mass of that material. Did you see mass represented as a property of thermal conductivity?

Full disclosure, less you mischaracterize anything I have said about myself. I am not a "so called" engineer and I have not represented myself as an "expert". I have given my relevant certification and represented my opinions based on my knowledge and experience in the field. I am not capable of producing the predictive model that you demand, though I believe I have a grasp of the key factors and variables. I believe that I am capable of creating a valid test for a specific set of control variables, but in all candor, I have no desire to do so in order to satisfy your skepticism. If you want proof by predictive model or testing, you're going to need to invest your own time, material and knowledge to do that.

It isnt about satisfying my skepticism. It is about you bringing numbers to the table to back your claims regarding why cf barrels dont cool faster. We arent getting anywhere either, so God bless and shoot straight.

If you have a contrary opinion, you are more than welcome to explain the principles which support your opinion as we have done. Swaying your opinion frankly isn't important enough to me to feel compelled to jump through whatever hoops you designate. Feel free to make your own model and I'll gladly poke a few hundred holes in it for you.

I don't need to present a predictive model or an equation to explain to you why you retain more heat if you wear a coat on a cold, blustery day than if you go shirtless and lay on a metal bench.

Because its what all the cool kids use, and also surrounds user with a veil of covid immunity!

Kind of like a hot dog in a bun? Or beer in a cooler? Or I think someone already mentioned a Corndog? All in fun!

Oh boy

If I want superlight build I would pick thin steel barrel.

Very good test for CF vs steel would be if we use barrels off the same weight and lenght one CF one fluted steel and shoot same factory ammo ,let say 50 rounds in the same rate and see what is group size and what is inside barrel temp.

I think that test will be very eyeopening.

 

[JAYgs8163]

I think steel barrel in this instance ^^^^ may be so thin to match the length/weight of CF that it would not be able to be fluted?

 

[josip89]

I mean for ultralight build I would use thinest steel barrel and that barrel can not be fluted for sure

But for test purpose i would use ,let just say two Proof barrels one cf other steel and fluted ,also same lenght (maybe 24") and weight.
For weight CF barrel I want that same weight fattest and fluted steel barrel.

In same caliber , I think 300 WM
And same rifle and make some test.

CF barrels are prob ok for a hunting rifle, but in my humble opinion, you are leaving too much on the table. Same goes for fluted barrels, I have seen far more fluted barrels that will not shoot than successful ones. Especially factory flutes, yuck.

Curious as to why fluted barrels don't agg. These are 416R stainless barrels, right?

Look at my original post it proves that a fluted #5 can weigh as much or less than cf wrapped

 

[longestrange]

To those who do not know us - TACOMHQ- along with long range optics we produce a type of barrel. It is not in competition with Proof or any wrapped barrel. It is not a light weight barrel and certainly not a mountain gun. However, if a barrel 32 inches long that starts at a weight of 6.2 pounds, is pound for pound significantly stiffer, well over 300% more cooling surface interest you -look us up. WE do cool the chamber and barrel by both a huge surface area (>300%) and active air flow thru the barrel.

OK had a look at your site and would like to ask why this barrel should work when a fluted barrel purportedly will not work for bench rest per Randy Tidwell who does a lot of that thing? You are using the same 416R as everybody else, right? Yours is 'internally' fluted from what I can see.

Maybe so but not in the same profile of barrel. They don't make CF barrels in that profile. Most are Varmint, Sendero, etc.
