6mm arc

Have any off yall gotten a chance to reload for this yet I have an upper coming next week and will be reloading for it since ammo is hard to come by
 
I am waiting to see actual results for this. After all the hype on the Valkyrie I don’t believe this will be any better.
 
I think the 6mm arc is what it is, a good ar-15 round and that is it. I wouldn’t own one in a bolt action there is a lot better other 6mm out. I’m planning on reloading a 100 grainish load for my son to deer hunt with he’s 8 and loves shooting my ar’s but is nervous about recoil. I’d like to mainly see how other reloaders experience with lighter reloads for varmints like 70 grain area.
 
From what i have seen on Johny's Reloading Bench and The Ultimate Reloader, it looks to be an excellent option.

I would be all over this, but can't justify tooling up for a new caliber when i don't shoot long range and, have an existing LR308
 
My buddy has been using one to good effect with the 108 factory load. I don't have any speeds to give you or any other data. He decided to hold off on loading since factory shoots well. I do know where there is a pile of the factory ammo for sale locally though.
 
A shorter necked down Grendel, hard pass...

This whole new AR caliber is completely stupid every 6 months and now with the ARC we are reducing powder capacity. And its "new"!!! Pretty sure the 243LBC has been around a lot longer. Don't leave out the new 6 Gay Tiger from GA Precision!!
 
A good alternative to a 6-223/6x45.
At least it’s factory.
I look at it like a 6PPC, a proven accuracy performer.
 
I look at it like this:

The 6mm ARC definitely has it's place for non-reloaders. For those who want something with more a$$ than a .223, but don't want to step up to a grendel when it comes to saving fur, the ARC will for sure fill that gap.

The issue I have with it is that it doesn't advertise or even get to the best feature of the 6mm caliber in my opinion. That is a predator/varmint cability along with a medium game and target.

They need to load up some 65gr or 75gr VMaxes in factory. Everything is about the long game and ELDX/ELDM/ATIP bullets. Hornady is missing the boat on this I believe.

I love the 6mm caliber. I have .243's, 6TCU and my beloved 6mm Mongoose...

If you hand load like me I'm not interested. There are way better options out there that beat or at least run with the ARC's numbers. My 6mm Mongoose will compete with the ARC. I admit the ARC will have more velocity, but the mongoose from a .223 case is giving me 2800 fps with the 87gr Vmax. Hit's on prairie dogs out to 300 with that load and has shot a 1 3/8" group at 300yds. I'm running 55gr SBK's at 3450 with 27.5gr of H322 and a cci450 primer. It's very impressive.

If I want something with more power in a 6mm I'd go 243LBC or 24GPC from Mad Dog Weapon Systems.

But I admit I don't know much about any of this.
 
I'm finishing up a 6mm ARC build and have 260 rounds of factory ammo only because brass is on backorder. I have various 6mm bullets to try but there just isn't any brass to be had right now. If you (OP) know a source for brass I'd love to know.

Do I expect the round to work wonders? No. But some of you guys are sticks in the mud LOL when it comes to tinkering, loading, experimenting, and just plain old having fun messing with various chamberings.

Does a new/different chambering always have to offer a distinct advantage? I don't think so as shooting, hunting, and reloading are my only hobbies and trying new things is part of the fun for me.

I have various AR's in .223, 6.5G, 6.8SPC, 6x45, .30 HRT, TAC 30 (barrel on the way), .50 Beowulf, and now the 6mm ARC. Future plans include a .458 SOCOM and .375 SOCOM just for fun.

I'll be using mine strictly for hogs, yotes, and deer at 300 yards and in so I expect it to work just fine.

I think the 6 ARC will suit the biggest potential market out there for the "bigger/faster/heavier than a 5.56" market in AR-15's nicely becuz:

1. I think they are probably WAY more potential shooters desiring to stratch their yardage legs with an AR-15 than there will ever be predator hunters? This is Hornady's target market, most shooters, not some of them.

2. It is Hornady factory-backed - they tend to do well with new cartridges, and research and develop them well,

3. They apparently already have a military market for the ARC?

4. It is factory, so dies will not be $100-200/set, but prob $35, and there will be factory ammo and brass available - HUGE for the vast majority of shooters, which is generally not those of us on this site,

5. It lends itself well to an upcoming 22 ARC release, possible 6.5, etc. etc.

6. It is close enough to all the various wildcats in velocity, versatility, etc., such that we shouldn't waste time arguing miniscule details that the vast majortiy of shooters wont even comprehend (yeah, that's gonna happen!!! LOL!) The average buyer wont care about 100 fps, or 1/4" difference on under 1 moa groups if he doesnt need to fireform, reload, etc. etc.

7. It'll do lil varmints all the way up to medium game with good bullet selection and shot placement.

8. It'll sell more guns and ammo.......

It would seem the arguments against it are the same as the arguments probably used against the 5.56/223 vs the 222/222 Mag/etc. back in the 60's when developing the AR in the first place??

I personally like the idea of more factory choices with less hassle. JMHO. Flame away.
 
I can't imagine the cartridge is gonna take off if components don't become available anytime soon. Shooting way over yonder with shorter cases, less powder and longer, heavier bullets out of a platform that is probably inheritly less accurate due to it's mechanics seems counter productive. I do think it is an provement over the 5.56 though. I thought the sleek high bc valkyrie had already taken care of this need?

Well said, new rounds don't have to change the world, it's just for fun (mostly).

the 6.5 "arc" already exists.. its called 6.5 Grendel. basically the only difference between the two besides the bullet diameter is a small bump back (0.030") on the shoulder of the arc vs the Grendel.

The 6 ARC case is shortened up between 0.025 and 0.030 depending on if you are looking at trim length etc. According to WIKI the ARC has 34 cc of H20 on board. My 243 LBC will run from 35.6 to 36.1 cc depending on brass lot.

What military branch is shooting it or who made a contract for it? I'm not saying Hornady is lying but companies stretch the truth about that. It could've been something as simple as SF ordered a couple rifles for testing. Im just curious.

Now that you bring it up, I dont know that I have seen that info anywhere?? Good call. Of course, there's always the out of "unnamed special units" or some such innocuous stuff?
 
The second one of those"groups" buys a batch for testing we are told it's been"adopted" and the manufactures make hay while the sun shines. I'm still waiting on the first truly deployed 6.8 SPC SAW.

So I went out and tried an 80 gr Berger fb with Imr 8208xbr because id like to predator hunt with this and my best 3 shot group was right around 3/4 an inch with most 3 shot groups being about an inch and a quarter nothing insane accurate but I believe when I load up a heavier bullet for a deer round it will probably shoot a little better. I'll mess around with this a little more but for the distance I'll be shooting it will be fine.
