22 arc bolt
- Thread starter joseph-98
- Start date
Its one of the funnest calibers i have... insane speed 3300-3400 with a 75gr and the recoil of a 223 bolt gun
Barrel length for these speeds? It'd be nice if someone came out with some good high quality brass for these. Likely more an AR cartridge where a lot of people just let the brass fly, but it'd be nice to have an option!
So i converted 6.5 grendel brass to "22arc" and its starline and seems to be working great... whats crazy is its only a 16 inch barrel.. 6.5 grendel and 22arc brass are almost exactly the same...
Yeah its does pretty good, and the recoil is a beautiful thing lol.. its alot of fun lol
So i have tried
62 gr hornday vt
75 gr eldm
80.5 bergers
And i still habe to try the 85 berger and the 90 vld
Looking at building a 22ARC bolt gun. Are you guys pushing those high MV's seeing any issue with bullets deforming or coming apart? I have a 1/7" twist 6mm Creedmoor that is ripping bullets apart if I go above 2950fps. I'm worried that the cartridge is more designed for AR platforms and MVs.
No issues at all.. what barrel is on you 6 cm what bullet you using? My 6 creedmoor is over 3100fps and good to go
It's a custom barrel by a local manufacturer. I wanted to run DTACs so got the 1/7 twist, but couldn't get them so ended up with the 108gr ELDM.
I hear Berger's have a stronger jacket but I haven't tried then.
Use a 219 bore 5 or 6 groove pipe, stay away from 218 bore anything for a 22 build. Especially if you want speed.

Cheers mate!
I didn't even know you could spec the bore. I'll talk to my barrel maker and see what he says.
Ruger is making the Gen 2 Americans in 22 ARC. Not top shelf, but a cheap way to get into the game.
3300 with 75’s…..phew!
I’m only running 3150 with 75’s in my 24” .22BR with LVR, but, admittedly, I’m not leaning on them. They just shoot soooooo freakin’ good there.
I NEED a good .223 bolt gun. I MIGHT .223 AI, but the .22 ARC just keeps beckoning.
A so-chambered Howa Mini would seal the deal……

Brownell's has the mini actions occasionally, haven't seen a 22 ARC yet, but its just a matter of time.

Guys have been opening up 223 bolt faces for grendel case on the tikkas. I opened up 65cm bolt to magnum dimensions on a Tikka and it's works perfectly.
What would you like to know brother? I started shooting the 85.5 berger hybrids at 3080... 29.5gr of cfe 223.. thing shoots about 1/2 moa pretty Consistently...prob one of the funnest guns i own
Man just curious how its been going. I have a 22 cal suppressor in the safe with nothing to put it on so I wanted to throw a 22 cal bolt action together more than likely on a tikka like you did.
Trying to decide between .22 ARC, .22BR, and .22GT....
Would like to run 16-18" barrel and if I could get velocities comparable to yours the .22 ARC would be plenty. Just wondering if you just happen to have a super fast barrel as those numbers you are putting out are amazing. I would probably run a temp stable powder which would give up some speed to the CFE.
Also the recoil on this think is just dumb... the gun doesn't move at all ... such a joy
Yea I am sure it is a blast.
Just trying to decide if I want to go with the BR or GT to get a little more speed out of the short barrel or stick with the ARC and keep the barrel life and factory ammo.
I could go with a little longer barrel maybe a 20". If I can get 2800 plus out of the 85.5 berger or the 88 eldm with a temp stable powder that should be plenty
BR and GT will give you more room for better powders. You can get pretty impressive velocities out of 22Grendel but you're limited to ball powder. BR and GT also give you a .473 case head bolt compatibility. GT functions in unmodified magazines. BR and GT brass should be more durable since you won't be pushing them as hard.
Something is not adding up here. First you were getting 3300-3400 with 75s out of a 16" barrel, but then later you were getting 3090 with 62s out of that 16"? The lighter bullet was significantly slower?
Was that 3300-3400 perhaps for the 24 inch barrel you mention later? That would make a lot more sense. Still quite impressive. I'm shooting the 75 ELDM about 3350 out of a 20" barrel, but that's a 22 Creedmoor burning 41gr of powder.
Yeah I don't think you woul have any issue getting 2800 out of a 20... the other one we built i think was 2840 out of a 20. I was using leverevo in that one and that powder really gets you the speed if you need it lol
I was but the brass was the issue when we were smoking them out there and I went from 31ish to 28.5 the speeds I was at at first were not sustainable.. the brass was struggling and you would get erratic groupings.. so I decided to turn it back a bit. But those speeds are obtainable my gun just want having it
This was 31.5 leverevo
Sorry I didn't keep that good of notes on this day but this was either a 68 or the 75...

Grendel brass is designed for pretty low pressure. There isn't a bolt action brass specification so anything past an anemic AR15 load is technically over pressure. When you lean on the brass it doesn't last very long. When you really really lean on it, like you posted, you'll be lucky to get more than a couple of firing (if that) out of the brass. If you can buy cheap once fired 6.5G Hornady brass, and size it to 22G in a single pass, smoking the brass may not matter.
For sure.. I was using starline 6.5 g brass and at the 3300 it was like 3 firings... now at 3050-3100 I'm on 6 haven't lost any yet
When you look at total cost of ownership, there's no free lunch.
Here's a model breakdown @ 63k psi = 1,999 shots.
Let me know if there's any errors on the inputs...
