22 ARC

[Tx_Aggie]

The 22 ARC should be an accurate cartridge, it's almost identical to the old benchrest 22PPC.

The shoulder on the 22 ARC is 30 thou further forward than the 22PPC. According to Hornady it's quite literally a 22 Grendel.

 

[45-90]

The shoulder on the 22 ARC is 30 thou further forward than the 22PPC. According to Hornady it's quite literally a 22 Grendel.

Yep, as I figured, the shoulder a bit forward almost identical, .030" shoulder increase won't make any practical difference mostly cosmetic, so it wouldn't fire in a 22PPC unless it had a little excess head space.
Almost half of the .030" could be taken up in head space max tolerences between the two cartridges. The slight increase might be 12 fps in velocity, barrels and S/D would determine which was slightly faster...if loaded to the same pressure, but the PPC can be loaded hotter by far because it was never intended for an AR 15.
All these cartridges come from the Russian 7.62 X 39, which became the 220 Russian then added SR primer . The old inaccurate AK 47... Just before that the 222 Rem was the accuracy king, and Walt Berger won benchrest matches and records set with the 222 Rem, invented by Mike Walker of Remington, where the 223 Rem & 5.56 Nato spring from.
So yep, a 22 ARC, a 22 grendel, a 22 PPC, standard, or 40° shoulder, highly improved, by many over the years. Just AK 47 brass with a small primer pocket necked down to 6mm and 22 caliber was found to be very accurate in 1974. So big whoop, Hornady and their new advanced rifle cartridge line...none of it's "new."
They just standardized the old wildcats, gunsmiths were making for their accuracy and long range customers...but I'm glad they do even with all the hype, because this allows more people have access to these already proven ideas..50 yrs ago...without an expensive gunsmith, and long wait time...plus certain customers get ahead of others inline.
Nothing new, its all been done before.
Reminds me I got beat in a match, by a a 225 Winchester...very accurate. A long time ago,
If anyone recalls what that caliber is. Being a 222 Rem fan for that sort of endeavor.

Wait, you consider 30 thousandths to be just "a little excess headspace?"

What would you consider to be a lot?

 

[Rio Precision Gunworks]

It has about 2 more grains of capacity. Plenty practical.

 

[45-90]

Nope, you're not interpreting it right. These cartridges are "almost" identical.. .030" length at the shouldet is no performance gain. You most likely could chamber the shorter shouldered 22 PPC shoulder in the 22 ARC and fire it.
And could "almost" about half way there depending on chambering and brass sizing, chamber the longer one in the shoter chamber made 006" deep chamber still in and if one is chambered to the max and it could go to .008" deeper, but should not, plus .002" to .005" for the The cartridge cases are shorter than minimum to fit all chambers, a hard hand on the bolt of a long chamber and a short cartridge could chamber...not likely but possible, for sloppy chambering and bad reloading....But you could be half way there, easily, as stated.

So the point is these two cartridges are that close, ...over sizing and too deep chamber could take up half of the .030" difference.
This cartridge was somewhat popular 40 yrs ago...but the 6 mm version is still going strong, as the 6 mm was found to be more accurate for benchrest purposes.

how would a brobot like me with some new 220 Russian brass convert it to 22 arc?

…lube and size with 22 arc die?

Probably very much, ...very endearing to be sure!

 

[TnDoc]

Ive been sheding light on this cartridge's performance for over a year now labeled as the 22 DPC (Desert Precision Cartridge). The dimensions are almost the same besides the freebore is half of that of the 22 ARC and 22ARC is based off 6.5 Grendel go gauge. 22 DPC is off the ARC case gauge (.030 difference in length). Im really excited to see Hornady take notice and get this into the market. We have these available in 18 and 22in AR15 barrels. Desert Precision Gunworks. 80gr SMK's are pushing 2940 FPS with Varget at 57K PSI (tested with pressure trace II system) 18in barrel

What magazine is used in an AR15 for 22 ARC? I've got an upper coming and 88 grain Hornady. Thanks

 

[SupressYourself]

Any 6.5 Grendel mag should work. People have different opinions on which one is "best". I like the ASC mags.

 

[tsu45]

Anybody shot up enough factory brass to be reloading it yet?

Nope, still waiting on usps to find my barrel.

What are thoughts on using N133 to load 22 ARC? I am using it in my 6.5 Grendel with 90gr Noslers and have great accuracy and speed.

If it’s working for you in the Grendel at a similar barrel length and you’re going to be shooting heavies in the 22, might as well use it as a starting point.

Thinking grendel, br, and dasher common powders will be in play depending on barrel length and projectile.

CFE223 always did the best for me in an 18” grendel shooting 6.5 107 smks.

 

[TnDoc]

Did you have any issues with temp sensitivity?

 

[tsu45]

Stoked to get some feedback on how the proof factory prefits do, especially on the shorter lengths they are offering.

My six yo wants to shoot his first deer next season. I was ready to set him up in .223 around the 77gr tmk when I saw that proof is going to go the arc in prefits. Thought it might leave some flexibility on purpose down the road when he grows out of .224 for hunting. That said, I hope he shoots enough at the steel range with his daddy that it’s burnt out and a moot point!

 

[Bevo]

Shot my Rainier 22” today w/ factory 88 ELD-M.

2765 fps avg. SDs were in the 10-14 range. Accuracy was meh. 1 MOA-ish.

Going to load 77 TMK with N133 and see what I get.

Also have TAC, H335, and Lever. Going to pick up CFE223 when I can. Hopefully N133 produces the result that I want since that’s what I have the most of.

 

[mjspeers]

I’m waiting on my barrel. Anyone running Varget with 62 eldvts or bullets in that 60-70 range?

a 62 grain Barnes TTSX with AR-Comp or CFE223 propelling it should work well in that role.

Varget may be just a smidge slow on burning rate, but every barrel is different and yours could have a sweet tooth for that combo.
CFE 223 / AR-Comp / IMR 8208XBR / TAC may be a little better starting point if you have those powders available.

For faster I’ve got some ARcomp, but a good amount of H4895. Any messing with that?

 

[SupressYourself]

H4895 works well in my 6 Grendel variant. It's not as fast as Lever though.

 

[NFshooter150]

I just have a few question about this lil guy.

1. will hornady provide reloading data soon or am I going to be waiting a year while they publish a new book?
2. how long before this ammo hits the shelf?
3. how long before I can get a factory bolt gun in the caliber (CZ600, Savage, or a Ruger)?
4. I wonder if I can now use the 95 SMK with this?

I am very excited about this new caliber but I am still a little leery. I mean I wish that they did a full push of the 22CM instead of ONLY filling orders through Horizon firearms. I think the 22CM would of been a better factory option, I could of possibly bought ammo through a brick and mortar. But now, 22 ARC may be the only way I can get a modern high performance "22" from a local store.

I also feel like the 22arc will be another Valkyrie. It will be hot for about a year or two and then die out to the next shiny new caliber Hornady comes out with.

Ya but 22cm you wouldn't be able to run in an ar15..

 

[Bevo]

Well its -20 outside with a 30 mph wind so i aint shootin any groups now. But a kind gentlemen sent me 20 62eldvt bullets and i got then to 3300 fps with cfe 223 powder and there is more speed potential left. Also shooting the 53 vmax at 3470 fps with great accuracy.

@Farmerbrown32 What was your load with the 62gr ELD-VT?

I am testing N133 and Lever this week with the 62gr. CFE delivers today so I'll try that next.

Just something Rainier specific. I think they went "MOD2" when they changed barrel blank providers several years ago.

Thinking of taking advantage of Natchez special and stocking up on a powder for the barrel I'm waiting on. They have N133 and AR Comp 8lbs in stock. AR Comp is running almost $100 more. I have never used N133, and have about 3lbs of AR comp sitting around.

For an 18" AR platform, what might be the best extruded powder for 62gn? I just am not a big fan of running ball powders, it was a pain in my V4, but it's not quite as bad in a ST.

I’m not familiar enough with n133 to offer an option on it specifically. If I was in your position the ARcomp would be a good place to start as it so versatile in a lot of the other cartridges I shoot. Anything “over bought” can go to work in something else.

N133 will be faster than ideal burn rate for the 62.

This was with a 224 Valk & 62 eld-vt. Powder burn rates should be the same as 22 ARC.

Best extruded I've tried with 62 has been XBR (Accuracy)
H4895 was + 40fps & didn'r group as well
Lever was + 140fps & shot tight.

I may give N135 a try next, but XBR & Lever both shot great.

How does Lever do with temperature stability? Hoping to use this gun on song dogs in the cold.

How does Lever do with temperature stability? Hoping to use this gun on song dogs in the cold.

IME Lever likes to be tuned on the upper end for pressure. I find what I consider safe max pressure & then back down a bit. What I've seen is that when Lever starts to come into tune the SD's drop. I try to stay in the low-mid end of that window with low SD.
When Lever is run in the window I described it burns clean. Although it does have temp sensitivity, it doesn't seem to be all that sensitive when run up near max. My 77RDF Lever load mid 40's to low 90's temp is within 20fps in the Valk.

If Lever is not run near the upper end it's dirty & all bets are off for temp stability.

Cfe 223 works great in the 22 arc and works great in a progressive.

Yeah I currently use it with 22 Grendel but I'm not the biggest fan of it. Temperature sensitivity and inconsistent accuracy for me.

I tried it this past weekend just to get a feel for velocity. Shot Berger 85.5 LRHTs (26.5-28) and 90 A-Tips (26-27.5). Max velocity 2780 and 2740 if I remember right. Notes aren’t in front of me. Last charged over pressured with ejector marks. Seems like a similar experience when I ran this powder in 6 arc. Ho-hum velocity and really dirty.

Will try CFE223 and also maybe H4350. Primarily interested in shooting 80-90gr bullets. Not a lot of data out there since more people looking at it as a varmint cartridge it seems.

This is an AR with 22” proof steel barrel. Shot factory 88 ELDM at 2800 fps.

 

[abn31c]

Following for info....
Barrel showed up yesterday, going to try 62 eld, 75 eldm, but really want Berger 70 vld to work. Love that bullet.
Still deciding whether to build new or rebarrel a DD mk12.
Also hoping rl16 works with the heavies.

Edit, got n540 to try also...

I feel like StB Match should work better but right now I’m underwhelmed. I do have a real easy load for it in my 16” 223 carbine so all good there for usage.

Loaded up some stuff last night. I also have and am curious about R16 but given how chunky it is and maybe a little dirtier I’m holding off on loading it, but hey why not maybe soon.

Would love to hear more experience with the heavies.
