Bartlein barrel help

[Heimdall2]

I am building a 6.5PRC and have a Bartlein CF #13, 22” on order with GA precision. The rifle will be a mountain hunting/NRL hunter rifle for me. I will use a brake and suppressor depending on the situation.
The build:
-HNT26
-Lone Peak Fuzion (alpine cut)
-Trigger Tech Diamond
-Nightforce NX8 2.5x20
-TBAC Ultra 7

I’m starting to have second thoughts about the #13 and 22” length. Thinking the extra weight of a #14 and 24” might be preferred for NRL Hunter matches, and less prone to POI shifts after 3-5 shot strings. GA Precision also informed me the Bartlein CF barrels don’t have the same accuracy guarantee is a Bartein steel barrel.

Anyone have thoughts, experiences, advice? Anyone recommend a Bartein steel over the CF for accuracy? If so, 3B? 4? Other??

Thanks in advance, it’s my first full custom build.

I have the exact same build: #13 22”barrel, trigger tech diamond, TBAC ultra 7, Lone Peak fusion Ti action but in a McMillain Game scout stock. The question to you is, what’s the intended purpose of the rifle? You said Hunter/NRL matches but I would personally rather have a different gun for each discipline but I admittedly don’t know how NRL Hunter matches work. Mine is purely hunting, so I went CF. I shoot 5 shot groups without any stringing. Haven’t gone beyond a 5 shot group without letting it cool. 22” gets me right at 3,000 fps with the Berger 140, and -2850 fps with the Berger 156s. Barrel hasn’t sped up yet imo.

I’ve never done an NRL hunter match, but I would think steel is your go to for any competitive match where multiple strings of shots are fired. It does have an advantage over Cf.

My concern would be more surrounding some velocity loss with 2" shorter barrel. Sometimes it doesn't matter much at all. But sometimes it can be a huge swing in speed sirens on the load. Velocity isn't everything. But I sure like to have as much as possible. Seems like 24" is a very popular length for the 6.5 PRC. Have two currently, with a 3rd on order.

One of them is a CF barrel. We only shoot 5 suits or so at a time. Haven't noticed any stringing.

I have a very similar rifle as what you are wanting to build. 6.5prc with a 22" Bartelin CF barrel on a Defiance AnTi action. Accuracy is great from my rifle and is on par with the steel Bartlein, Shilen and Lilja barrels I have on other rifles.

I feel it balances well in the Manners EH1 stock. If I had a 20" tube I'm sure I'd be happy with that also.

If you are wanting to do competitions, I'd probably go with an all steel barrel. What I've noticed is how the CF barrels heat up compared to the all steel barrels. Barrel mirage is noticeable in fewer shots through my CF barrels than it is with an all steel barrel. Perhaps my observation has more to do with my CF barrels being chambered in PRC cartridges, perhaps it is the barrel construction? I'd be curious to hear other opinions.

If I thought I would need to take 5-10 shots in a short period of time, I'd likely not have a CF barrel. For hunting, I enjoy the accuracy and light weight th CF barrels provide.

I have a 20 inch Bartlein #13 7PRC with less than 100 rounds so far. So far I love it. Seems to be accurate with whatever I put through it to this point. I’m waiting for the barrel to speed up before I try to dial in a load.

Hey thanks for the replies everyone. Makes me feel more confident in sticking with a carbon 22” barrel. Ended up going with the #14 in 22” as they ended up not having the #13 in that length. Should have the barrel in a couple more months!

I have 1 hunting gun with a carbon bartlein and a pile of steel ones in various rifles. The carbon barrel luckily does hammer however im not sure if go that route again over just a smaller diameter steel just for piece of mind.

You don't need the extra velocity in a PRC for NRL so I'd not worry about 22". I'd be more concerned with it being a little unwieldy with a can while hunting. My 22" SAUM stopped getting used with the ultra7 after a season of doing it because it was a bit unwieldy.

That rifle is going to end up a bit on the heavy side to me for a "mountain rifle" but everyone has their preferences on that. Those Bartlein carbons aren't light. If doing steel, i wouldn't go heavier than Bartlein #3 for a hunting rifle.

My sample of 1 bartlein carbon #4 in 300 WM shoots good. I've babied it a bit compared to most my rifles though and not gotten it piping hot.

I’d have a tough time spending carbon money on a barrel chambered in 6.5prc. Especially if shooting matches with it.

18” bartlein 3 would be perfect.

For nrl you just have to make power factor, you don’t need extra velocity.
