Accuracy king of the small cals?

[L.Sherm]

I think all 3 are gonna be so close it isn't gonna amount to a hill of beans in the FPS category. Ive become a long neck fan and Lapua brass fan the Alpha brass I gotta try so if I did any of them it would be off either Lapua or Alpha brass with the longer neck especially if i wanted to shoot 39-55 grain bullets.

FWIW, the 22ARC IS a 22 Grendel. As I understand it, when Hdy did the 6mm ARC, they shortened the Grendel case so that it could feed some of the heavier (ie 105gr) projectiles from an AR mag. When they dropped down to 22cal, they were able to keep the original Grendel dimensions and still feed the 90gr pills.

As far as the 22 ARC/Grendel being a 22PPCAI, I'd say that's exactly what Bill Anderson was going for when he developed the 6.5 Grendel so it wouldn't surprise me if a 22PPCAI was an absolute ballistic twin to a 22 ARC.

As far as the accuracy of the 22ARC goes, I'm curious about this myself. Based on the almost legendary performance of the 22 PPC and 22BR, I'd expect it to be outstanding. I would think that the brass would be the weak link regarding its accuracy potential. The only factory 22ARC brass I've heard of is from Hornady. If you start with 6.5 Grendel brass from Lapua or Starline and neck it down, I'd expect the end results to be on par with the PPC and BR cartridges with the velocity being somewhere in between. My personal interest in a cartridge like this would be for prairie dogs. I'm on a budget, so being able to easily form 22 ARC brass from comparatively cheap Starline 6.5G brass and ending up with something that rivals a 22 BR sounds pretty appealing....

My 22 arc is strictly starline 6.5 grendle brass
Considerably cheaper and super easy to form a false shoulder when necking down the case.

I’m having a 22arc on a CZ 527 built right now. Should be done soon. Hopefully it drives tacks

I shot Jon Newman's 22 waldog once and don't see how anything could be more accurate. He quoted me a price and I tried to haggle, when I made my counter offer it was gone. A neighbor bought it and it sits in a closet, after Jon passed i don't think anyone she knew had the knowledge and tools to load for it.

Now THAT is a cry'n shame!!!

Keep us posted. There just doesn't seem to be a lot of info out there about how difficult/easy the 22ARC is to load for, or what it can actually do from a 26" bolt gun with the various bullet weights. I've wondered the same thing about the Valkyrie. The limited information I've found on that cartridge indicates that some people have had a hard time getting it to shoot accurately, and other people had no issues at all. Then there's the question of what a person considers to be "accurate"... Hopefully the 22 ARC gains a little more traction so there's a wider breadth of information available for it.

In a 24” gasser I’m pushing 80’s at 2900 and I’m within Hornandy book data.

Accuracy has been good enough with standard case prep that I just got to the speed I liked and started shooting it at steel without even doing any seating depth testing.

I’m liking it.
Kinda reminds me of my 6BRA.

IMHO, that's pretty good for a gas gun! I've always thought that Hornady's 22ARC load data was a bit wonky. Up to 75gr, most of their data lines up with what I get from a hot 5.56 load. I guess it makes sense though, that on the 80-90gr stuff, a 5.56 runs out of case capacity, but the ARC case has the room needed to push them a little harder.

The bolt gun data, on the other hand, seems all over the place. It seems odd that the 53-55gr stuff is only 100fps faster than a 62gr load, but a 75gr load is over 400 fps slower than the 62gr loads (and is barely faster than the gas gun data), but then you only loose another 100 fps or so when you jump up to a 90gr bullet. It doesn't seem to mater how I look at the bolt gun data, it never really makes any sense to me.

Has anyone messed with the 22arc yet? It’s basically a 22ppc so I’m thinking it should be just as accurate

I just rebarreled a rifle to 22 ARC, so far 5 shot in the .3's. H4895, Fed205M, Hornady brass but soon Alpha brass. ARC Nucleus action, Krieger barrel 26", McMillan A5, 3511 fps with 62 ELD-VT. Max Hornady published load.

Any pressure signs? Did it take much work to get it to that point? To me it seems like the 62gr ELD and ELD-VT seem like they would be ideal for these cartridges (PPC, ARC, BR).

Another vote for the 222 have an old Sako that flags put a Douglas barrel on in 1971 still shoots .2s with 4198 and hornadays 50 sx very dramatic.

 

[Idaho-Lefty]

That .222 1/2,.. Looks, pretty Sweet to, me.
Sharp Shoulder, not much Body Taper + Long Neck and Just ENOUGH Powder space to, "get it, Done" !
Perfect for, the Short, Rem 700, Action.
Who Has Dies for, it ??
a 1-12 Twist and 53 gr. V-Maxes, look to be,.. MADE for that, thing !

DIES I think you would have to have your gunsmith make them when he chambered your barrel unless you could find a used set somewhere . PT&G don't even show a reamer for it any more.

 

[NC/Br Shooter]

I have a XP100 action glued in and a new Hart 24" barrel in 222Rem and now have 589 on the clock . Been seating the bullets into the rifling and this gun don't like that so I jumped it .006 this time and what an improvement . All the info is on the target . Todays target 4/2/2025 smallest 3 shot target was .103 .

was that me and you shooting that day Art?

The 204 Ruger holds it's own

... just about Swift speeds

 

[Gabe22BR]

I’ve advoided this thread best I could-

1st case design
The ppc case has won more than any other-
20ppc
22ppc
6ppc
Then we go to the 223BF
222 has its fair share
222-1/2 has won
Then
20VT has won a few matches

Have not seen where a 223 has ever won nor a 204 ruger..

That said- I have a 20ppcai on the drawing board…

I was pondering a 20 WalDog after you posted the pic of that SCREAMER target.

It’s actually closer to a 22 Grendel and is just a hair under a 22BR in capacity. I would expect it to perform very well given my bookend experience with the 22PPC and 22BR.

A key piece of “accuracy” is that the case capacity matches the burn rate of an available powder, with the additional variables of bullet, throat design, and barrel configuration. All the “most accurate” combinations have all these variables in balance.

How do you match burn rate and case capacity? I do look for around 100 % case capacity but how do you know a burn rate and capacity are matched up? Thanks just trying to see another way to pick out powders.

20pup be better…. But hey, I got too many dies, barrels now..
