Sure would be nice to know what smiths are doing a switcharoo, always someone in the mix doing shady crap.

Ummmm.....no no difference!
Even in normal steel 200 rounds is out of the ordinary. I myself have never seen that. Not even feedback from ammunition testers that we make test barrels for. At most I’d say normally a 100 rounds.
Awesome innovation Frank! I just have two questions:
1.) Can it be nitrided to further increase the barrel life like 416R and CM can if done with the proper process?
2.) How would the barrel life compare to 4150CMV and similar "stronger" CM barrels?
Great news I was just getting ready to order a 6.5 barrel from y’all. I wouldn’t shoot either your old or new product out but I have sons and grandsons so I’ll see if we can’t get this old fat mans So Paw Smoke Pole fixed!2 minutes ago
Bartlein Barrels is pleased to announce the release of a new barrel material. Working with the mill and testing different types of material and tweaking the material over the last few years and with testing having been performed by ammunition makers we now have a different grade of material that we have had made and is proprietary to us.
- New
- Add bookmark
- #33
The material has been proven in lab testing and in outside real world testing to provide a barrel life that is 1.5 to 2 times longer than the standard 416 grade of material.
We are calling the material 400MODBB. Pricing for this barrel material in standard diameters/contours etc...will be $555.
As always there are a list of things that effect barrel life and we cannot guarantee everything a 100% but for an example as I know it will be asked....in 6.5CM ammunition pressure test barrels are normally pulled from service at around 1700 rounds. The new material doing the same type of ammunition test work the barrel was pulled from service after it had 3500 rounds on it. We've had several 6mm's in calibers that the barrel normally is pulled around 1500 rounds go 3000 rounds.
We and or the customers that have done the threading and chamber work have had no issues with machining. I will say your reamers will not last as long but nothing that would really concern me. It does machine a little different but it's not horrible to work with.
So you will have a choice of the standard 416 material from us and the 400MODBB material.
Any questions it would be a lot easier if you emailed us at [email protected] or called in directly at 262-677-1717 but I can only imagine the amount of questions we will be getting and with everything going on in the world currently I'll ask you to be patient for the replies.

Are you planning to machine some AXMC/AXSR barrels as well? They need thicker barrel shank, and don't know if that's an option for the 400MOD blanks.
Hi,
Here is my opinion on that concept....
1. The internal barrel steel still gets the maximum temperature and flash point burn inside it, no matter what is placed externally of it as a "heat absorbing filler".
2. By the time the heat reaches the exterior of the steel barrel aka the fill material...the part of the barrel that fire cracks has already taken all the heat as if it were a "traditional" barrel.
NOTHING IMO is going to increase barrel life unless it touches what burns/erodes the barrels out and that is done internally not externally.
Ceramic metallization and even sapphire metallization is a cure to heat erosion and fire cracking but nobody is ready to pay 8k dollars per barrel type thing for a manufacturer to recover the R&D cost over the span of the market shelf life.
Frank and his crew have put in the leg work and the MONEY work...buying an entire mill run of anything is not cheap, especially once you start talking about modifying its' chemical makeup from "run of the mill" alloys.
In a world of "New Normals", lol.....I am looking forward to this new normal.

There is always a benefit to carbide over HSS. There’s is no disadvantage that I can think of past the cost.@Frank Green If one were to order a new reamer to be used on the 400MODBB material, would there be any benefit to using Carbide rather that HSS?
Not sure I’ve ever seen a barrel take 200 rounds to settle in

Would the same advantages to using carbide over high speed steel in every other application of manufacturing not apply here as well?No advantage.

@Frank Green - I just want to thank you for taking the time to present this information and answer these questions.
There is a very large number of very experienced and highly knowledgeable members here on the Hide (and I'm def not one of them) but its outstanding to have a premier manf come on the site and offer up expert opinions and information first hand.
Now, just out of idle curiosity, I gave some thought to the discussion above about barrel features tried to pull heat out of the bore. Its been MANY decades since I took any thermal dynamics courses but my vague understanding is that such features may dissipate the heat faster but will absolutely not do anything about the almost instantaneous peak temps reached, for example, in the throat. Basically, they may increase the heat transfer coefficient but do nothing about the initial thermal load. This will shorten the time that the material is at temp, but not the peak temp.
But I really don't know what I'm talking about! hahaha
Cheers
Looks like any other rifle in a xlr chassis
I don’t have any personal experience other than having a couple of them on order. I’ve talked to some sponsored shooters (however you want to interpret that) and heard numbers up to 3800 rounds on a 6BRA that was still performing to a PRS match level.Anyone burn one of these out on 6mm PRS build?
I am getting one spun for a dasher, curious to see what real world life to expect is.
Why? You think they know more about barrels than the guys that make them?this is very interesting..I need to see what GA thinks about these.

I think just about all their builds are done with bartlein barrels and they have more experience with this you do and since they build some of the best rifles out there and build all my rifles i will see what they think about it sorry if that bothers youWhy? You think they know more about barrels than the guys that make them?
We've had about 5 different guys burn them out already. 6BRA and 6 Dasher type guns. One guy is on 4k+ rounds and it's still shooting last word we had. Most of the guys seem to be around 3000 - 3500 rounds or so but haven't officially considered them done. One guy pulled his at 3300+ rounds and put a fresh stick on for the PRS Series Finale just to be on the safe side but the old barrel was still shooting.
Another shooter and Spec. Forces soldier is taking his rifle to the finale. It's a gas gun in 6x47 Lapua and he is running his 105-109gr loads at 3100fps + and the barrel has 2k rounds on it. He said he normally pulled his barrels at 800-1200 rounds because they where toast. Also is currently testing a 300 Norma and that is at 2k rounds also.
The reason why he brought this up is because @Frank Green is Bartlein barrels. He is the one who came up with this in the first place.I think just about all their builds are done with bartlein barrels and they have more experience with this you do and since they build some of the best rifles out there and build all my rifles i will see what they think about it sorry if that bothers you
i know but not disrespecting Frank because all my guns have his barrels but I trust the guys at GA and will get their opinion. I don't see the problem with get 1 of the best gunsmiths opinion before getting a gun built with this barrel?The reason why he brought this up is because @Frank Green is Bartlein barrels.

Doesn’t bother me a bit. It just shows that you Don’t go to the right places for the best information. George and crew are awesome, no doubt, but they aren’t going to know more about a new steel alloy than the guys that worked to get to developed and have been using and testing it long before it was public knowledge.I think just about all their builds are done with bartlein barrels and they have more experience with this you do and since they build some of the best rifles out there and build all my rifles i will see what they think about it sorry if that bothers you
Not asking them about what atoms make up the steel..I am going to ask them about their experience with the barrels if he tells me to stick with 416 then I would go that way. If he tells me to give it a go I will. But I guess next time I should just ask you because it looks like you know everything....even what questions I was going to ask but please keep telling me what I should be doing when spending my 5,000 bucksDoesn’t bother me a bit.

You are making a lot of assumptions on here.Hi,
I hate to be the bearer of flip side of asking gunsmith's about new alloy.
1. They do tend to make money on spinning up barrels so you would be asking someone that potentially stands to loose money. (NOT referring to ANY particular smith, just in general logic conversation).
2. They do tend to NOT be very expedient at accepting "changes" within any aspect of the industry.
3. Willing to wager we see the same sort of "pushback" and syrup slowness of smiths pushing ModBB as we seen when "prefits" starting becoming a thing.
4. Please let us know what alloy analyzation machine that any smith has in their shop.
5. Please let us know what TESTING procedures any smith have done to come up with their conclusion aka OPINION on the regular vs new alloy.
Sincerely,
Theis
