Running on every imaginable ammo isn't a criteria of any professional group I've ever seen. It's a pretty stupid criteria really.
Noveske DDF Barrels

100% for my serious ammo, I use single lot # batches for each rifle. Everything else is training ammo.
Missing the point entirely. No professional group would be put into that situation. As they have close to unlimited funds and supplies.
This is a situation where professional experiences is now placed in private situations.
I am done with this thread. Too many narrow point of views.
You mean, too many people who disagree with you?
I do not see the point in a rifle that is tuned to run absolute trash ammo. All of my guns are ported "small" according to you, and they run great even on steel case, in my limited experience with it. My Hodge is a 14.5" middy with a 0.072" port, as I recall. It runs great. My other rifle is an 11.5 carbine with a 0.68" port. It runs great, too. I am not trying to run 3rd world handloads "because what if!?". Each rifle has its ammo that it shoots well, and I stock up on it by the lot #. All else is plinking ammo, and is fine. As we saw half a decade ago, if you don't already have the ammo, you won't be getting it. 5.56 near evaporated. I think there is a better argument to be made in "stock good stuff" vs. "Get a trash gun so you can run anything you find" just to have it double-feed and outrun mags with certain cans and ammo unless you put a stiffer spring and heavier buffer in it and...see what I mean? Just run something that's vetted and works well and be happy.
Who exactly are you referring to here? Mercenaries/contractors? Again, I don't know of a single professional organization that has a requirement for every conceivable ammunition. Most (all?) have a very narrow ammunition selection.
Is this one of those gay discussion from LF or M4C where some tard stomps his foot and types in all caps "STAY IN YOUR LANE"?
I mean, if anything, “military experience translated to private life” would dictate to stock up with as much of a very small list of ammunition as possible. Ain’t no professional planning to run around and scrounge for ammo caches.
Just showed up today, I’m looking forward to trying it. This will be my first experience with the 6mm ARC.
I took it out for the first time on Saturday, I had some Nosler 95gr bt’s on the self that I used for break-in, starling brass, and 29.0grs of CFE223.
Once I got used to the feel of the rifle it printed a few groups that were sub moa, and one that were all touching. I’m not much of an AR shooter so I’m pretty impressed. With real load development it think it will be a solid shooter.
Has anyone else tried these out yet? Got my 18” out today finally and my experiences match J Max’s. My best couple groups were about MOA maybe a bit bigger. This trip was more so for function/break in/tuning than precision grouping. The lower I had it on has a basic milspec trigger with a good bit of creep so I tried taking the groups with a grain of salt this trip. It definitely opened up towards the end though. No rapid fire. Let it cool a bit between 5 or 10 rd groups, but not all the way down. Only got 60rd on it today. My next trip I’ll be running a SSAE so hopefully I can get it tightened up as it breaks in more.
FWIW mine is not a noveske build. Just their 18” DDF barrel and bolt in a mega mml upper

Didn't Noveske publish the dimensional requirements for their DDF barrels? I think I have them somewhere meaning anyone could flute a barrel in the same manner. Seems kind of strange they released three common lengths when the actual length of the barrel should be taken into account to achieve the stated results/properties, no? 5/8x24 threads on the 5.56 would be great.
My 18” 6arc tightened up a bit the second outing. Was getting around .8 - 1.1” 5 shot groups with factory Hornady 108’s prone from a bipod and rear bag. I’ve got about 120rds on it now and probably get out to shoot it again next week. Haven’t decided yet if I should give it a cleaning at this point yet wait till after this next trip to the range.
I fully understand the range of “clean it fully between rounds for the first 20 rounds” and “what’s cleaning?”
Early on, me personally, I say a little cleanliness is next to can’t hurt.
I’ve come to be a believer in the Montana Bore Conditioner. I always shoot suppressed, seems to stay relatively clean by pushing a wet patch followed by a dry patch at the beginning and end of most sessions
I also swab all new barrels with it meow before shooting, I think that’s the real secret sauce…

I don't have the DDFs specifically, but within our family we have multiple Noveske barrels in 556 and 6.5 Grendel and they're all capable of sub MOA with factory ammo, and the 6.5 Grendels specifically can consistently shoot .6 MOA with Hornady Custom SST and/or Black ELD-M.
I'd be tempted by the DDF for cool points but for the fact I can't find fault with any of the existing barrels...

Pretty crazy how deep these flutes actually are.
And the bore looks amazing through the bore scope.
Just a few more parts to come in.

I was surprised too. The top edges are almost sharp to the touch. The weight reduction is nice though
Is anybody seeing POI shift from heat sooner with these DDF barrels? Mine will be used in gas gun matches where 20-30 round strings wouldn't be uncommon.
I haven't even built my upper yet but I'm wondering if the DDF at 34oz is any better than a Douglas, WOA, or similar at 38-40oz.

Allegedly the DDF flutes were designed in conjunction with TACCOM to prevent such shifts.
So if that is true, it should be better than "regular" barrels. But it would be interesting to see what real world results say.
My Noveske barrels from late 2023 look like they were cut by sharks with friggin laser beams on their heads. Consistent .6 MOA 5 shot groups with factory Hornady. I've struggled to get a relatively quick 10 shot string to hold 1" re: when they heat up, but this isn't fluted, plain old round 20" .750 6.5 Grendel.
I can’t speak to longer strings, I’ve only shot up to 10rd groups with it and still working on breaking it in. I’m limited to factory ammo so trying to see how tight I can get it with that. My 10rd groups were shot earlier on and probably around 1.5-1.75MOA. I will say it does appear to cool noticeably faster. The barrel doesn’t feel at all hot after a 10rd string.
I guess I should have done more research on my intended use before 'pulling the trigger' on the DDF. 
I’m just curious to see other people’s experiences with them. We’re pretty early buyers of these. I’m not as experienced shooting precision gas guns as I am on bolt guns.I guess I should have done more research on my intended use before 'pulling the trigger' on the DDF.
I'd be surprised if you don't have a functional final result. I don't regularly fire 30 round strings but at the end of the day my question would be more along the lines of - if the Noveske can't, would the others be able to without a significant increase in weight? Does the accuracy degradation actually translate to something that really impacts your ability to hit as necessary?I guess I should have done more research on my intended use before 'pulling the trigger' on the DDF.
I concede 30 rounds is somewhat of an extreme case. Normally there would be 12-17 targets at the gas gun matches I shoot, so maybe 20-25 rounds would be a more realistic expectation, also depending if it's limited rounds or unlimited.
But the answer to both of your questions would be, yes for me. The other SPR barrels that are somewhat heavier in weight in the 38-40oz range, very well may resist their POI shift longer from the heat and longer strings of fire. 4-6oz additional barrel weight may or may not be worth it depending how large the POI shift from the heat is.
And yeah, accuracy degradation impacts hit ability to me, since it seems the shots later in a string are likely to be later in a course of fire and likely further out. The further targets may (or may not be) be larger so the moa could be similar or even more generous, but a barrel that goes from .7 to 1.5 or 2moa (or more) will have a negative impact. I say further out as in 600-700y.
I just don't know what the potential POI shift from heating up could be with the DDF, and when it starts. The claim of the flutes helping with cooling quicker isn't all that relevant to me since a typical stage par time is 90-110 seconds.
I get easily distracted by big words and shiny things.
