I have a proof barrel in my Desert tech srs chambered in 300 NM and I can't get it to shoot anything consistently. Cold bore shots are almost always extra erratic. I don't think this barrel is any good.

Is there any carbon barrels worth using? I see carbon six does blanks for desert tech's.

The carbon six on the 338 terminators has been great with most shooting lately between 920 to 1070 yards. Cold bore in the group with most groups around half moa some more some less but very happy with them. If the group gets around 1moa it’s the wind or a bad shot.

My 6.5mm Proof barrel has been great. But there have been some folks on here that haven’t had great luck with their .30 cals. So you are not alone.

I have not been happy at all with the PROOFS 30 cal and above with over a dozen used. I have seen some 6.5' shoot ok, especially since the finally went to 5 groove in the smaller cals.

We have always seen the Christensen Arms barrels shoot very tight with dozens tested from .223 to .338

We have tested at least 6 barrels from CarbonSix from 6.5 to .338 and they have shot great. We just got 6 more in.

We just got in two 30 cal Bartlein's in and have been hearing great reports on them too.

That's as far as we have gotten so far.

I have tried a few carbon wrapped barrels over the last few years.
  • Proof; in 6.5 Max, 7 max and 6.5x47. Nothing but good things to say on these and have been very accurate.
  • Christensen Arms; too many cartridges to list and all have been shooters. One I am taking to So. Africa for a hunt of a lifetime.
  • Fierce in 30 Sherman, 6.5 PRC and 300 win mag. All 1/2 moa.
  • Preferred Barrel Blanks; 6.5 sst. Kind of worked up a 1/2 moa load out to 500 yard with the 156 gr Berger but I need to explore it more.
  • Bartlein; my first will be ready in a few weeks.
  • CarbonSix; my first just arrived but needs to be threaded and chambered.
My preferred carbon wrapped barrel contour is the magnum, Proof Sendero, M24 or Christensen Arms barrel blank, which seams to be larger than what comes installed in their rifles.

Thanks for all the input. I have had good luck with christensen arms as well but they don't make a desert tech contour. Its good to hear that carbon six barrels have been performing. I was thinking about Bartlein as well.

I hate to write this proof off but I just can't get any consistency out of it. I tried 230 atips, 215 bergers and 225 eldm's with H1000, retumbo and N170. I would have liked to try 230, and 245 bergers since it's throated more for them than the 215's but I can't get any. The problem is even if it would shoot one of them decent I don't think the cold bore fliers would go away.

I'm very early into load development, but the Bartlein CF 300 WM looks pretty promising. Shot a pressure ladder with it a few weeks ago, and it wants to shoot very small. Can't wait to have time to develope that load.

I have only tried proof and Bartlien. Hard to go wrong with a Bart. Others may be just as good. But I haven’t tried them.

All my Proof barrels (8 to date) have shot great. One pressured up way too soon however, and I pulled it long before it was shot out, due to frustration.

I have three Bartelins now, and they are absolutely amazing so far.

Just for reference though…..we’re any of these 30 cal and up?

I am happy to report my new Bartlein carbon fiber barrel is starting off great on my Ridgeline. It is a 22” 30 cal (30-06 throated long). I only have 40 rounds through it. Enough to do a pressure test, a course and fine seating test, but it has been super consistent so far. I shot this today with Badlands 175 BD2s.

+1 for Bartlein CF

I'll give another vote against Proof 30 cal. On a full custom built by Defensive Edge. worst shooting gun i've ever owned. i should say barrel because when i put a Bartlein on it, steel, it shot bugholes!

I've got a Proof 300 RUM that shoots lights out. Have a Bartlein carbon in 338 Edge that also shoots lights out. No complaints with either...

My Bartlein CFW 22" #13 shoots incredibly well. I have a 28" Bartlein CFW in MODBB steel in 300 Norma that shoots in the .4s but admittedly it is much harder to shoot small due to the energy and recoil. IMG_20220218_121236400_6376.jpg

I have 4 proof carbons. 2 are 300wm’s. They all shoot lights out. Honestly couldn’t shoot any better. I did just buy 2 benchmark carbons to try on a couple new builds. For no reason other then I like trying new things and they were on sale last Black Friday.

I went with 1 sendero and 1 sendero lite. Also grabbed an additional sendero for a buddy. Hopefully they shoot as good as they look.

I have a .30 proof seems to be a 1moa barrel. Fine for what I do but I was expecting better. I haven't looked into bartlein can you get the similar contours in bartlein??

On the proof barrels, FWIW, After talking to a respectable gunsmith, some smiths cut the muzzle brake on the tang that is to be removed. It happens to be the same size that is the base for a 5/8" x 24 thread.
This is where the lapping tool is turned around and wallows out the bore.
Just what I was told.

I cut threads on the tang on two or three barrels before I just started cutting it off. I've seen no difference in accuracy but, then again, I'm not shooting benchrest with one. Proof will tell you to cut that off for the reason you state.

I have been having luck with the Bartliens. The truth is, I have seen a lot more issues with carbon barrels than steel barrels (not the Bartliens so far) And I chamber a lot more steel barrels. When I do a job I really want it to shoot well. Sometimes I can be picky about components because I would rather pass a job up than do one knowing it probably wont shoot. A bad barrel is one of the most frustrating things there is. The carbons do have a purpose. They fill up large barrel channels without being heavy and they do look cool. They are not stiffer and they dont handle heat better, dont buy into that. The fact is the carbon wrapping process can hurt accuracy if its done wrong, it cant help it. If everything is done right it wont hurt it. I dont have enough experiance with all of the newer options out there to have opinions on them.

I'll throw in another recommendation for bartlein CF barrels. I have a 26" #4 CF 30 cal that is shooting really nice. No regrets in the extra money spent over straight SS.

I have a muller works barrel that’s wrapped by Pederson precision llc. It shoots lites out, was not finicky at all for load development.

Personally I cant wait for the carbon trend to pass. I chamber a lot of them and while most of them shoot well, the rejection rate is off the charts compared to steel. Even though I chamber probably 10 to one steel to carbon, at the end of the year there will be far more problems with carbons than steel. In general its rare to get a bad steel barrel, even one all year. And Im chambering many hundreds every year. Its most disappointing to me because I hate building a rifle that someone struggles with. I think if you plan things out both ways, steel vs carbon you can get to a similar weight. Keep in mind a skinny steel barrel that weighs as much as a carbon is still all steel. I did a test a few years ago. Stiffness vs weight. I pulled out a bunch of barrels and supported them by the shank in the same place and hung a weigh the same distance out from the breach and measured deflection. Now these were proofs back then. I found that the defection of an equal weight carbon barrel was the same as an equal weight steel. If memory serves, a #3 fluted was as stiff as a sendero light. I think they both weighted about 3.5 pounds. So there is no gain at all. The wrapping process can only induce stress, it cant reduce it. Just something to chew on. I dont mind chambering them, I always have them here getting chambered. Some guys really like them and I do not try to talk them out of them. Im just so disappointed when someone struggles with one of my rifles.

HaHa. Your first sentence made me laugh. A similar comment many have made over the years about the 6.5 Creedmoor and what you hear about the PRCs. My first choice will always be carbon wrapped barrels.

Well those comments are just coming from people that don't like change or new things. I love new things in the market. If there has not been a lot of problems there wouldn't be a thread like this.

I have only bought/used Bartlein CFW barrels, and will only use them for future builds. No sense messing around...

Given their popularity, would think technology with carbon will continue to improve. If so, I'd have a hard time believing carbon will be just a trend. I'll never own another custom build that doesn't have a carbon barrel. And more than likely it'll be another Bartlein.

So what’s the advantage of a carbon wrapped barrel vs a fluted steel barrel? Weight? If it is weight then it can’t be much. I’m thinking simplicity here. One piece of steel vs steel and wrapping.

I am having my first carbon-wrapped (CarbonSix) for my .338 NMI, build in progress.

Our C6 338 barrels are performing great! Gene was very helpful when we had questions and I felt his customers service was top notch, win win!

I have a CarbinSix 28” magnum contour chambered in 338 Terminator on a BAT HR. Can’t wait to get to it this winter and try it out. My first C6.

Agreed! Gene helped me decide on the proper contour for my intended purpose.

I have a Benchmark on my new 300 RUM build. I have a little over 100 rounds and it shoots great. It is right up there with my Krieger and Bartlein barrels on my bench rifles. I would buy another one

Anesthetics only. I'm getting ready to chamber one in 308 Obermyer but need to replace an M24 steel barrel so the stock is forcing the issue. I agree with Alex, with CF barrels there is more risk in having issues than with a plain steel barrel.

I look forward to your results. Their pricing is attractive especially now through the first of the year.

My #4 30 cal Bartlein CF is shooting as well as my #4 Bartlein SS barrels at a fraction of the weight.

I have a Proof Sendero on my 264 WMI that shoots in the 1s pretty consistently.

I have 2 Hells Canyon barrels I’ll be testing out this weekend; 6.5 RSAUM Improved & 300 Norma Improved.

I have used several so far. The very best have been the Christensen Carbon barrels and also CarbonSix. I have used more of the CA's but that is changing as Daniel Ryan Ladd and I keep testing the CarbonSix's. At this point both CarbonSix and CA's have all shot very well with multiple of each used.

Jeff,

That’s very comforting to know. Thanks!
