6mm arc bolt gun?

You didn't offend me. While I have nothing but respect for bench rest and target shooting, (without which many great cartridges would never have been designed) for my use I don't give as much weight to target performance as I do practical use.

I'm of the opinion that the AR I5/M16 in 5.56 NATO was as good as it was going to get 58 years ago. In fact it was so good that it has seen very little improvement nor much in the way of serious competition until recent developments in propellants.

Having carried the M2, the M14, the M16 and CAR15, I've been of the opinion for many years that for us civilians as well as the military the AR platform has been and will be a significant performer for many decades.

I have been waiting for a cartridge for the AR platform that covers as many of the bases between defence and general purpose usage out to 800 yards as possible for nearly 50 years.

From my experiance a quality built AR rifle has the credibility as a platform. A 6MM projectile at 2,600 FPS while a bit light for large game, in the hands of a practiced practical rifleman adequately crosses the divide from close quarters tactical to practical hunting, truck and scout rifle, as long as you stick to the 52,000 PSI limit.

My advice is if you build an AR stick with a single manufacturer for the upper and lower. The chances of it all fitting like a glove are much higher, I went with Aero Precision as a complete upper assembly was available, the lower was also Aero but I used custom fire controls.
I bought my first Colt A/R soon after joining Marines in early 70's. The military M-16's I shot, the Colts A/R's I subsequently bought and every other brand I fired up until about 15-18 years ago were NO WHERE NEAR as good as what could be put together up until 15 - 20 years ago. Why? It wasn't so much powder - it was the better barrels (not to mention braked and with bull barrels) , free-float handguards and far better triggers. I'd have never wanted to use my old A/R's for ground squirrels trips back in the 70's. I don't leave home without them now - and I use surplus powder that may have come from the 70's.

My AR15 A2 is better then any service rifle I had but my Aero Precision M4E 6MM ARC has clearly superior metal work. The A2 shoots the 68 grain real well, the M4E shoots the 105 real well but the A2 has a synthetic spacer to tighten up the lower and upper. The M4E didn't require it.

I would not want a talented rifleman shooting at me with either. With the A2 I'd feel ok making windy day shots at 400, the M4E I'd feel ok at 600 on a windy day.
 
What kind of velocities and pressures do you expect to load for?
Sorry for the delay. Was really after a deer hunting load for the 6mm ARC & moved forward W accuracy 1st & velocity a distant second priority. For this deer season I ultimately settled on the 108 Berger Elite hunter over 29.4 GR of LVR. Muzzle velocity of this load from my rifle came in at roughly 2780 FPS.

Was very pleased with my experience of 1 deer taken with the CZ 527 at 250 yards with the 6mm ARC thus far.

That's good results both in terms of ballistics and game taking. A 250 yard kill with the 6MM projectiles is good work.

I expect as we all have more time for development the 6MM ARC will be a real shooters type of cartridge. Efficient use of powder, good for lightweight short actions, repeatable loads and accuracy.

My M4E Aero Precision AR15 has really surprised me. I was concerned because we all know how quality can be as rare as a unicorn today but impressive results with factory ammo.

Good luck with it keep us posted.
 
Recently put together a fairly comprehensive lead up & this deer hunt account for this CZ 527 re-barreled to 6mm ARC over on another form.

 
Sportsman warehouse carries the Savage Switchback in 6mm arc.
Looked at one today, nice Imo.
Heavy bbl, muzzle brake you can remove for suppressor, target bolt knob, 20moa rail.$549
 

Howa is coming out with a version of their Carbon Stalker Mini in 6mm ARC soon, product pages like that have been leaking out over the past month.

A 4lb 10oz hunting rifle in 6ARC sounds awesome to me. The only downside I've found with the ARC is that to get top velocities with heavies you really have to use LVR, CFE223, or AA2520, all of which are temp sensitive. If Winchester ever brings out their long-rumored Varget speed Staball, I think it will probably be the perfect match for the ARC.
 
I have or had 6mm ar turbo 40 improved, 6mm ar, 243 lbs and a couple of grendel.

The turbo 40 improved is awesome. Pushing 105's easy 2850. The 6mm AR and 243 lbc lose about 100 fps from the turbo. That is why the 95's are more popular.

6mm arc loses more case capacity so will be slower especially with the 105's. They should have made it ackley improved and pushed the 95's. But then i am not hornady. And i still don't own a creedmoor.
I too have shot the Robert Whitley 6mmAR TURBO IMPROVED 40 for years! Looking at the info on the 6mm ARC the Turbo walks away and shoots quite well at 600-1000 yards from an AR Platform don’t think the ARC will perform as well. I also shoot the 6mmSLR. This is another fine cartridge from Robert. Just another sales gimmick to me!
 
Howa came out with their 2022 catalog, and it looks like they added 6mm ARC to most of the mini line:


The only bummer is that instead of sticking with the SAAMI 7.5 twist they seem to have gone 8. At least according to the Berger stability calculator, that can leave some of the heavier hybrids marginally stabilized at lower elevations.
I didn’t see a barreled action in that catalog(may have overlooked), have you heard of this being available?
 
I bought one of Whitley's 6mmAR uppers immediately when they came out and it is a great round. I shoot the 6PPC and 6BR in bolt guns and would recommend either of them ( along with any of the 6mm or 6.5mm great rounds out there.) it's a commitment to start a new caliber, brass, dies, etc.
 
With all of the buzz about the ARC....i cant help to think this might be my new round to play with. Im building a gas gun asap....but also considering doing a bolt gun.

I dont see any manufacturers jumping to build one yet, but i assume (hope) this will change soon. I mean....this is a poor man's br size case with plenty of factory ammo given hornady putting it out.

Whats the consensus?
I have quite a few local gun shops around me an a Bass Pro. I also go to four regular gun shows in the area ans have asked about the 6mm ARC at every shop and show. None have had or seen any ammunition for the cartridge. I'd like to have one made by rebarreling an 1885 Winchester or Ruger No. 3~!

Please consider the energy of the .556 against the 6mm ARC at 1000 Yds. I think that you'll be amazed at the advantage of the ARC~!

I'm considering building a 6mm ARC on a single shot Winchester 1885 action. We've been hearing and reading about this supposedly "amazing" cartridge for a while now, but I have yet to see any ammunition or components for sale in gun shops or gun shows. Nor have I been able to find anyone who has seen any. I found a high end 6mm barrel that would have to be chambered and threaded to fit my action, but I'm reluctant to buy it and get into the build if this situation is going to be the case well into the future. What's Hornady doing about filling the pipeline~??

Amazed is an understatement. It's also still super-sonic at 1000 yards. I'm really interested. Now all you have to do is find ammunition and reloading components. "Rots of ruck~!!"
 
Just bought a Salvage 110 Tac in 6mm ARC.

Should be here Wed.

Was going to buy a Proof, but didn't want to drop $3200 on a rifle since I haven't even shot an ARC yet. Numbers are impressive though.

I'll have some experience after the weekend.

$630 shipped for a NIB Savage 110 Tactical will atleast give me a cheap/accurate option to test the round out. Make a heck of truck gun with the 18" barrel.

I've been able to buy 6mm ARC ammo at my local gun shop occasionally, and it's been pretty consistently available online:

Brass has been the real issue, I've never found Hornady cases in stock, so I've just been buying factory ammo and reloading the cases. It kind of just is what it is though, they Intro'd this chambering right when demand for components and ammo was skyrocketing.

If you're worried about case availability, you could just chamber for the 6mm GT instead, I've had no trouble getting GAP marked Hornady brass from GAP or Mid South. 6mm bullet availability would still be an issue though.

Too me, the 6mm ARC is Hornady's answer to the 6.5 Grendel. While I love my ARs, the Bolt gun platform works for the ARC as it does the Grendel. The ARC edges out the 6.5 grendel in performance slightly. I think in a bolt gun it'd be a good option. My buddy's son is building one on an AR platform currently. He's pretty excited about it.
