Just finished a build with a Proof CF in 308 for a mid-weight hunting gun that I could still take out on the weekend and shoot matches with. Going with a CF barrel was my only option to keep it lighter weight but still able to handle some strings of fire. I've gotta say I've been very, very pleased with mine! With that said, there's no way I'd spend the extra money if weight wasn't a concern on this particular gun. I haven't noticed any other benefits of carbon fiber other then weight. I shoot it just as I do my steel barrel and it doesn't seem to act different, but I generally don't put more than a mag through any barrel without letting it cool afterwards.
I didn't know you could cerakote them either, but when I saw one cerakoted I had to black out the chrome!

9.5lbs as pictured and the only sacrifice I made for weight was going with a lighter scope. Otherwise it's got everything I normally wouldn't put on a hunting gun (stock choice, full pic rail, precision rings, and muzzle brake).

Very nice! What is length of that one? I’m doing a 6mm CM with bravo chassis and ordering a proof.
Sounds like hearsay from someone who heard something from someone who ... Might be more of an illusion than a mirage. Then again it all depends on humidity and temperature, in some sweltering jungle 5 -8 ...A buddy of mine is claiming that his buddy can only shoot 5-8 rounds of 300wm before mirage was so bad. "It dissapated heat so fast he couldn't see shit". He's claiming it to be a hunting gun only, not a range gun or comp gun.
Although I haven't been following this topic, this is the first I heard about this. Has anyone encountered this? I'm looking to put one on my ar10 308 with a tbac u9.

Do you think the mirage was due more to the 300wm than the barrel "dissapating heat to fast"? That was my first thought. But then again, wouldn't that be a good thing? Cooling the barrel quicker, but coming at a cost of excessive mirage? I'm looking at putting it on a 308.
Once you get any barrel above 165 degrees Fahrenheit you'll get mirage, however with a typical PROOF Research Sendero Contour I haven't seen any after 5 - 8 rounds, unless it is a really hot day in a really humid climate. Maybe the friend of a friend should clarify a bit and state some of the particulars and environmental stats before we get someone to make a blanket declaration that "PROOF barrels are more prone to mirage, not ready for prime time, and basically crap". Hearsay negatives just don't have a lot of weight for me. Just sayin' ...I'm sure 300WM is making it worse but smaller cartridges have the same problem. Proof CF barrels cool more efficiently than steel which means more mirage.

I think a lot of the mirage might depend on the barrel profile. I have run 10-12 rounds through my proof practicing stages in 1.5-2minutes w/ no significant mirage coming from the barrel. Now, the suppressor on the other hand without a cover yes, 100%. It truly is amazing how cool the barrel stays compared to conventional steel

If you're talking about your AI, half of your barrel is covered by a HG/rail. It won't mirage the same way an uncovered barrel will. I have a Proof CF barrel under a 15" handguard and I can do mag dumps without mirage. My 6CM CF barrel only takes about 10 rounds before mirage is obvious. Obviously environmental conditions affect mirage but but side by side I can replicate it at will.
In process of building a 6.5 Creedmoor on a Mausingfield action. I'm curious if anyone has experience with Proof Research carbon fiber barrels. I'm not going to lie...I have a healthy obsession with carbon fiber stuff. I've heard they're slightly lighter than a steel barrel but not sure about any other benefits that come from them. If any of you have experience either way it would be good to know.
I'm told that Bartlein and Pac-Nor barrels are good too. I don't have a lot of experience with this so any help is appreciated!
Thanks in advance.
I've also posted some questions about triggers for this rifle here...if you've got input on that as well that would be great. Thanks!
I just finished a build with a Proof barrel - a 28" Sendero contour on a 28 Nosler. It is my first CF barrel, so my sample size is very small, but here are my initial impressions (up until now I have only ever used Bartlein and Krieger).
Cosmetically: The Proof is downright gorgeous. I am with you on carbon fiber; it just has a unique and awesome look, and the Proof is particularly well executed in this regard.
Accuracy: The Proof seems to be comparable to my Bartleins and Kriegers chambered by the same smith. Half MOA consistently, showing signs of even better. Only a sample size of one barrel though. I have had 10+ Bartleins/Kriegers all shoot lights out, so I am more confident when describing the accuracy of those barrels based on consistent, repeated performance.
Weight: It is not as light as you might think. It is definitely lighter than a steel barrel of the same contour, but the weight savings are not game changing to me. I saved about half a pound over a light palma steel barrel.
Finish: The biggest difference I have noticed between the Proof and my Bartleins/Kriegers was the level of carbon fouling. I don't know if that is attributable to the level of finish lapping, but I can say that all else being equal (powder, primer, projectile), the Proof fouls more and faster than my other barrels. Since mine is a hunting rifle that will never see extended strings, this isn't a big problem for me. The Proof also took way longer to break in than my other barrels (by break in, I mean the point at which copper fouling becomes negligible). I have seen Bartleins stop copper fouling in as few as three shots. I was still running multiple KG12 patches to clean copper out of the Proof at 60 rounds.
Price: Come on. We are talking about carbon fiber. You know what you are getting into.
All in all, I am happy with the Proof. It makes for an especially gorgeous rifle when paired with a carbon fiber Manners EH-1. For high volume target rifles, I will probably stick to steel barrels with cost being a main driver.
Is the life expectancy/round count really only 2500-3k rounds for a proof barrel?
I have a proof barreled 300 Win on a Nucleus. It is a good shooter with factory ammo, and I have yet to figure out a good load for it. But I have not put a lot of work into it.
Powder shortages have limited me to H1000, but I am almost out. I have tried 150 Grain Barnes X, 150 Grain GMX, 185 Grain Berger, ELDX and a few others.
Factory ELDX hunting shoots little bitty groups. Fatory ELD X Match shoots pretty good.
Maybe I should just shoot factory.
The barrel is a 28 inch 1 in 9.4 twist. I wish it was a 300 Weatherby or 300 PRC with that long barrel.
6.5 cm
Had Montour County build a 7wsm with Proof barrel and it shoots lights out. Plus it looks amazing, and is super lightweight.
I’d say that’s a minimum if your not getting stupid with it or want utmost accuracy.I think 2500 is reasonable on any 6.5 barrel with normal pressure loads
If I ever built a super nice hunting rifle it would be 7 saum with a proof.Had Montour County build a 7wsm with Proof barrel and it shoots lights out. Plus it looks amazing, and is super lightweight.
That is exactly what I did, I settled on a 24" proof.If I ever built a super nice hunting rifle it would be 7 saum with a proof.
All the 7mm short action cartridges arepretty awesome.
