We should start a thread keeping tabs on manufacturers releasing components for this round.

Going to be a very fun little cartridge.

I've vern shooting one since 2011 as the 22 LBC. I've been using a simple Redding bushing die to make brass.  It's a nice manageable round.

I'm looking forward to building one. Got on the wait list already for Odin Works 18" barrel.

Like the 6 ARC, I don't look for reloading brass for a couple-few years unfortunately.

It looks interesting

GLS, with your 22 LBC are you using the 1.525 brass trim length of the 22 ARC, or the 1.520 of the 6.5 Grendel, or some other?

Also, can you recommend a chamber and reamer print?

BTT

I'm generally skeptical, but if this round will pump 90 gr .224 bullets, like say the Hornady A-Tip or the Berger VLD, into the 2900 fps range out of an AR ( REF> LINK ) then I may look into it further.

Velocity for the 88gr load is not released yet?

Would not expect it to be near 2900f/sec. That is just shy of 243win performance.

DB

Box claim velocity is 2820fps. They usually test in a 24” barrel

I'm interested in how well this cartridge maintains velocity as the barrel is cut down. I'm thinking a 10.5"-12.5" would be a nice little hunting package, if it doesn't lose too much speed.

Maybe I'll be the guinea pig.

It gives off a sort of .223 WSSM'ish vibe.

Having done some comparisons, my experience has been the shorter you go the less improvement over the smaller cartridge case.  More powder needs space to burn and generate velocity, and the smaller the hole the more length you need.

That’s entirely true, but a short 22ARC will still shoot high bc heavy bullets and a 223 will not.

There is that, too

We will see.  Much hoopla was said for the V and that didn't create much more than a ripple.  Hope it prooves worthy

I'm going to change that with an SFAR here in the next little bit . 5.56 loaded to 2.5x" coal .

I’m interested to see where your experiment goes.  Good luck! (Sincerely)

Ah, thanks !

9D1Alpha,

Strongly suggest you try 22-250 or 22-250ai optimized for long heavy bullets in the sfar.

My thoughts are that it will work with existing magazines.

DB

Edited to add: .257 now has 117gr eld pills. Maybe a custom 250ai?

I'd do 250 savage if that were the goal .
* 110gr eld-x
** my thoughts on 5.56 long vs 22arc are 19% more operating pressure vs 15% case capacity.  Takes some work with mags but doable. Brass , bolts , bbls .
*** covers the 224 Valk and 22 arc...and 6 arc
**** above that I'd do variants on the .204 case ; 6-204 , 25-204 , 6.5-204 . All the case capacity and 19% more operating pressure .

22-204 2.7” is pretty much the dream.

I look forward to seeing the magazines!

Don't you just use 6.5 grendel mags or 6 ARC?

A Friend built a 22 Grendel and uses 6.5 Grendel magazines.   I’d try the 22 ARC in 6.5 Grendel magazines and would be surprised if they didn’t feed.

I think he’s referring to 9D1Alpha’s Ruger SFAR experiment (AR-10 sized mag well)?

SR25 mag with front ribs milled to allow straight windowed ar15 mag to slide in and then secured .

Double

I'd be more interested if I didn't have lots of 55 g. ballistic tip .223 and a new WO Predator upper.

Starline does runs of Grendel brass so that may be helpful with the 22ARC .

For Barrels
Craddock Precision
Shaw
Odin
Sgt of Arms
Proof SS
(added) Saturn
Also Proof Carbon Fiber Barrels, Around $900. I am not paying that much for a barrel. I have no problem with an H-Bar weight AR15.

Dies so far I have seen Hornady on the shelf.

Midway has Hornady Brass Listed as coming soon. Almost a Buck a round. You can sign up on the notify me list.
Case Gage also coming soon.
The ELD-VT Bullets are also listed as coming soon.
All Hornady ammunition coming soon.

I think I will have Brass or Ammo in Hand before I jump in the pond.

My math says buying loaded ammo for brass is not out of reason.
Loaded Ammo 62 ELD-VT  $31.99  or $1.60 a round

Reloading:
62 ELD-VT Bullets    $0.33
New Hornady Brass $0.94
Primer                   $0.09
Powder                  $0.17
              Total       $1.53

Buying loaded ammo for brass is how I had to do most of mine . Picking up components as they become economically beneficial.

22 ARC  24" Test Barrel  52,000 psi Factory Ammo Numbers.
62 ELD-VT  3300 fps  G1 = .395  G7 = .199
75 ELD-M   3075 fps  G1 = .467  G7 = .235  (Corrected)
88 ELD-M   2820 fps  G1 = .547  G7 = .274  (Corrected)

My research shows (Internet)  22 Grendel Loads producing more velocity. Probably at higher than 52,000 psi pressure I would guess.

For Powders it looks like CFE 223, H4895, RL16, H4350, probably Lever, and a couple AA powders should work fine. Possibly RL15 and RL15.5, and I am sure more powders will work.

For Coyotes the 62 grain ELD-VT should really shines. With a G1 of .395. It is Fast, Long, and Sleek out of the 22 ARC.
What I came up with as an estimate of performance. AR15 20 Inch Barrel 3100 fps. AR15 Scope Height 2.60 (Leupold Mark AR 30mm Cantilever Base). My math came up with 10.88 MOA Up Elevation at 600 yards. Quite a bit flatter trajectory than a 6 ARC with the 80 grain ELD-VT Bullets @ 2750 fps with 14.46 MOA Up at 600 yards. I also ran numbers on the 6.5 Grendel using the new 100 grain ELD-VT Bullet @ 2600 fps. It required 15.90 MOA up at 600 yards. Wind numbers were better on the 62 grain ELD-VT Bullet from the 22 ARC also.

The 100 grain ELD-VT in the 6.5 Grendel should really make it shine also. I have a 6.5 Grendel Compass Lake barrel on order. I have everything to make it run but the barrel. I had given some thought to re-barreling my White Oak 204 Ruger to a 6 ARC down the road. After running the numbers the 22 ARC would be a lot more of a performance gain over the 6 ARC considering I will have a 6.5 Grendel up and running before I do anything with the 204. With the good ELD-VT Bullets in the 6.5 Grendel it is so close to the 6 ARC that I do not see a big enough performance gain to justify two chamberings that are so close together in performance. I believe the new 100 grain ELD-VT Bullet will really wake up the 6.5 Grendel.

You would think that Hornady would be getting the 22 ARC Loading Data pages up on their web site. So far I have not located any reloading data specifically for the 22 ARC. It would be nice to figure out the best powders, and start gathering them up before ordering a Barrel, and Bolt. It would be nice to see what powders that Hornady has came up with that work the best in the 22 ARC.

Bob R

Loading data is up on the Hodgdon website.

Hodgdon 22 ARC Loading Data

Attached File

@bobR1 where do those ELD-M BCs come from? They are substantially lower than Hornady claims.

BC Numbers came from the Hornady Web Site. Do a search for 62 ELD-VT, 80 ELD-VT, and 100 ELD-VT. The Hornady site will have all the numbers on all three bullets listed. I just did a search to verify that my information was correct.
62 ELD-VT Product # 22762
80 ELD-VT Product #24372
100 ELD-VT Product #26103

I did come up with a different set of 62 ELD-VT numbers off a podcast. Must have had some discrepancies on numbers early.

I did not manage to come up with a link to the 22 ARC Hornady Load Data. I did find 6 ARC. Load Data.
My research indicated two sets of load data one at 52,000 psi for AR's and a second set at 62,000 psi for Bolt Guns would be available.

Bob R

You listed them as the 75 ELD-M and the 88 ELD-M not the 80 and 100gr ELD-VT.

I don't mind paying to play but I too am not buying a barrel over $500.00. The Odin offerings should be under that. Awaiting Ballistic Advantage's offerings as well despite the fact I'll never buy another one of their barrels in .223.

I'll most likely buy ammo as a means to source brass for the very reasons who mentioned, that's what I did with the 6mm ARC.

I don't expect the notifications to come in anytime soon for brass.

ETA- Spoke to BA today, no specific barrel length/profile info as of yet and they are looking at late Jan to early Feb for availability.

Deleted.

Ryan you are correct I mixed up my notes between the 6mm 80 ELD-VT, and 6.5mm ELD-VT and the .224 75 grain ELD-M, and .224 88 grain ELD-M.

I sent an e-mail to Compass Lake asking when they would offer a 22 ARC Barrel. No response so far.

I will probably contact White Oak also.

Bob R

Will 1:7 stabilize the 88gr ELD-M ?

It should, with 16+” barrels.

If going with a sub 16”, a 1:6.5 would be a better option for areas closer to sea level.

What barrels lengths are you guys interested in for 22 ARC?

12" CLGS

14.5" MLGS

16" MLGS

18" RLGS

20" RLGS

Other?

18" RLG for me.

16 rifle gas and 20 rifle plus one. If you make the gas system too short it’s a nonstarter.

Probably 20 Inch with Rifle Gas. I will probably go H-Bar or some other heavier profile. I will be looking for an accuracy build, not a light weight build.

Bowhunter The Odin offerings should be between $320 and $420 depending on what you order. I was watching a podcast with Odin. I am pretty sure that you can call them and make an order for a 22 ARC at this time. I am 100% sure they have a reamer in hand. My local gunsmith already has a Reamer and Loading dies on the shelf.

My guess is that until Starline comes out with 22 ARC Brass, buying loaded Hornady Ammunition will be the best and possibly only option to get brass.

Bob R

I was thinking 16" might be on the ragged edge . But I think it'll be decent at my altitude.  I'll certainly give it a try . Thanks

WARNING! Controversial Statement Ahead: "Plus 1" gas systems are gun store myth and are a difference that's not really a difference. They may also work, of course, but they work no better than standard gas system lengths, so why the extra hassle?

Starting with the 6.5 Grendel and its derivatives, standard gas system lengths, with proper port sizes and a sound build, work with 100% reliability. Using standard parts makes everything easier.

Bob, if Hornady hasn't released their final reamer dimensions cuz SAAMI has not yet approved it, what reamer and dies is your 'smith using?

I’ve ordered mine from Manson.

JGS and PTG have the reamer print as well, supplied by Hornady.

Thanks, last I spoke to them they placed me on their "waiting list" but I've yet to hear back, perhaps another call is in order.

Over a 20”, I’m going +1, over 22”, I’m going +2.

It’s less about reliability and more over having a soft shooter that doesn’t trash brass. I’ve seen brass from 224Valkyrie with a 22” with a +2 vs a RLGS. The +2 brass was less beat up. I’ve seen the same with 6.5creedmoor. The ballistic advantage 6.5creed barrels have shown they are phenomenal shooters, but I’ll never buy another simply because they aren’t a +2 gas on their 22”.


22ARC offers a lot of performance in an AR package. I’ll only use it in 22-24” gas guns and 26-28” bolt guns.

Why not just run carbine length gas systems on everything?

Why don’t you use a mid length gas system in a 20” barrel?
