Target shooting weight is generally your friend.
In reality this is a thin-wall STEEL barrel wrapped with carbon fibers. IMHO the only advantages a I can see are a bit lighter weight and better heat dissipation. But how much one can heat the barrel shooting .22LR? Not really much.
It seems quite a few rifles with standard steel barrels exhibit cold bore fliers as well.
With regard to which shoots better, accuracy will not be determined by whether the barrel is wrapped in carbon or not. Potential accuracy will vary according to the consistent quality of the bore.

I actually own a Bergara RBX carbon fibre I don’t have a ton of time behind it yet but I have some experiences and some opinions if you want shoot me a private message with your number and I’ll give you a shout.
I have the Bergara B14r in carbon and I can say that without a doubt it's the most accurate 22lr I have ever owned. The carbon barrel is stiffer than steel and therefore has less mean deviation than its steel counterpart. With the right ammo, you can get an honest 1/3 or less MOA if you do your part. Forget the steel, just get the carbon barrel, start researching your ammo and begin recoding lots (Eley and Lapua should be your go to sources) to find out what it likes and never look back.

Carbon vs steel barrel vibration is interesting. Can you give more information about carbon barrel vibration, perhaps some sources for more data?
The 3/4" group at just over 200 yards (about .38 MOA) referred to is extraordinary by any .22LR standards. It even surpasses the 200 yard .93" (.44 MOA) record
described in h ttp://bulletin.accurateshooter.com/2018/04/amazing-rimfire-accuracy-0-93-5-shot-group-at-200-yards/ The relevant section is reproduced below.
Australian John Lavaring recently shot a group at 200 yards that would make most centerfire shooters proud. The five-shot group, with all shots in the center 10-ring, measured just 0.93 inches. That works out to 0.44 MOA at 200 — mighty impressive for a .22 LR. Recorded at a Rimfire Fly Shoot benchrest event in Canberra, Australia, this 200-yard target set two new Australian SSAA National records! John was using ELEY Tenex ammunition.
Perhaps the 3/4" group (five rounds?) represents a Canadian record. Was it was due to a carbon barrel? Were there other especially good groups at 200 yards or was it simply a random act of accuracy?

It is written right on the target it was shot at 50m, which I would believe.
200m.. vid or it didn't happen lol

Gimpy - he didn't say that was the 200m target!
That said, Grey - I'm curious about the "sub-forum" - where is it and where are these '200m targets' ? I'm happy with 3/4" at 50 with my $400 B22, but still . . . not going to spend a grand PLUS to hit a nickel at 200 ^O^

Tactical Teacher / Barney was there when it happened. It's in on one of his threads here on CGN. We will see if we can dig up the picture again.
It was the best compared to other groups by .5 shot at the same time
Those other groups, which at .5" larger than .75", would be 1.25" (or .625 MOA). They are extraordinarily good results at 200 yards too, especially for a relatively modestly priced rlfle/system. With .22LR, the further the target the more difficult it can be to shoot MOA-size groups, let alone sub-MOA.
In your first post here, you said carbon was very good for "dissipating vibration". Are you aware of information regarding carbon barrel vibration?
I always doubt such outlandish claims of accuracy.You can probably outshoot most people that comment here, because you are an experienced target shooter.
We have done a significant amount of study on it. Enough to convince us to go into production and only sell carbon fiber barrels.
As to your question on why our modestly priced rifle that we claim to be as accurate as other significantly priced rifles available. We have a set price structure based on our cost and we are happy with our margin.
Perhaps as an unbiased and respected member of the community here you might be interested in a demo / loaner rifle to evaluate our claims.
As I mentioned before, the 200m groups were witnessed by tactical teacher. He has pictures of the group.
Thank you for the information provided on carbon barrel vibration.
Please note I asked no "question on why our modestly priced rifle that we claim to be as accurate as other significantly priced rifles available." I'm confident price structures are invariably based on costs and happy profit margins.
I would welcome the chance to try out a demo or loaner rifle, but it would be best to wait for next spring. I don't shoot at an indoor range, and my club range will become inaccessible as soon as there's snow on the ground. Furthermore, testing in cold temperatures is not reliable.
