Temp was 104*this afternoon. I tested one Hornady case with the 80gr eld at 29.4gr of varget. Got 10 firings and stopped there because I got tired of messing with it. Pocket is still snug and it’s ready for more. Left the gun outside the whole time so the chamber stayed toasty and I could get a better idea of pressures. Case looks fine, one very faint ej mark and that’s it.
Again this was running out of a Ruger Gen II bolt gun 20” bbl
29.4gr- 3020fps 80gr eld-m

Probably so, but I was only expecting to get about 3xs with that charge. Will start shooting some groups in the 2900 range and see how it does but running it around 3000 is tempting although pressure is probably higher than you want to be running.
I will check it tomorrow if I remember. Probably 63k-65k if I took a wild guess lol.
Picked up my Ruger American Gen II 22ARC last week. Vortex DB Tactical 4-16x44 FFP
At 110yds, groups were .7 (88 grain) and .4 (62 grain) Temp 100F @ 4000 fasl, humidity 19%
Will try again next week; I'll load 75 ELD-M this week to test now that I have a few cases.
20" bbl so probably lost 150-200fps(?) over the 24" Hornady uses to test.
Factory 88 ELD-M
Data from Garmin Xero
Factory 62 ELD-VT

That’s a good start, damn good groups with factory ammo and a factory rifle.
You will probably pick up a few FPS after a few rounds through it. My 20" gas gun picked up an avg 75 fps after 150 rounds through it.

Picked up a complete upper at Midway for $375 with a discount code. It's their AR Stoner brand, so I'll see how it shoots as it breaks in. So far it's shooting the factory 88s around .75 to 1.0" but the impressive thing is the ES and SD. Again, the barrel is speeding up and breaking in but in an 8 shot string the SD was 7.5, which isn't bad for factory ammo. I'm getting some fliers so I'll have to figure that out.
I have some dies on the way so I'll jump down the rabbit hole with you all.
How's the brass life out of a semi auto so far? It doesn't seem to be getting beat up too badly.

Is there really that much of an advantage 22 ARC over 6mm ARC?
Asking as someone who has a lot of 6ARC brass and loaded ammo and wants to better understand 22 ARC.

My main deal is shooting cheaper bullets and less recoil. Now is it really much less I haven't shot them both in the same day. I have a couple 22 arc uppers and using them for varmints. Not really lr target shooting.
Berger 85.5gr Hybrid. .524 G1 $0.39 a piece. 2900fps in a 20" 22 ARC
Berger 105gr Hybrid. .536 G1 $0.50 a piece. 2600fps(?) in a 20" 6 ARC
I had 75 ELDs up to 3150 in 20" ARC but that bullet has just never been consistent for me in the 4 different cartridges and guns I've tried them in.
I'm curious to try it in mine. They shot lights out in my factory 8 twist Remington in 223, all the way out to 1k if you could see impacts.
I don't own a 22 ARC, no interest in it.
You already have the 223, it takes more pressure, in the AR by design, cheap brass, cheap loaded anmo everywhere.
For small deer I'd prefer the 6mm ARC, where a 22 cal is illegal to hunt big game.
I saw a video where a guy shot 60 coyotes out to 700 yds and many closer ones on a full run hundreds of yds out with 108 ELDM factory ammo...it has pretty impressive killing power on coyotes.
The 6mm ARC would have longer barrel life than the 22 ARC.
One can run pretty hot loads in a 223 bolt gun with longer COAL, and the 223 Ackley version was popular in the Varmint Hunters club yrs ago.
The Cooper Challange.
"Putting 20rds, in a 20 inch circle, in 20 seconds, at 1000 yds", was accomplished with the 223.
My favorite 6mm ARC load in the 18" AR barrel is 108 ELDM at 2667 fps Ave with low S/D, and Leverevolution powder.
It's very accurate in the Proof barreled ARs.
But for light bullets the 6mm ARC leaves something to be desired, in velocity.
So I don't use light bullets in it, mostly 107 SMK, 108 Eldm, 108 Berger, 110 SMK, 112 Barnes, to 115 Dtac.
Then I have a 6 lb AR 10 in 308 with 16" barrel shooting 168 ELDM at 2756 fps, with 1/2" 5 shot group accuracy....easy to carry and fairly good at longer ranges....but I wouldn't use it in a prairie dogs town.
So for general shooting, varmint hunting, these 2 new ARC cartridges don't really offer much over the 223...especially if one goes to longer COAL, and use the BobSled to drop in long cartridges. Or a binary trigger and run over 1000 rounds per minute, for plinking fun, the 223 already does this pretty well, very cheaply, so one can shoot alot.
It's up to the individual, to decide, I like the 6mm ARC because of its accuracy, and performance with heavy bullets is pretty good, for an AR 15.
For close range AR 15 knockdown power, it would be a fast 16 twist barrel in 450 Bushmaster with 500 gr jacketed bullets in large bear country, like Alaska, not a good varmint cailber. But one can make shot shell cartridges for it for small game.

That's why this really is so subjective. Because I had the 6mm arc and thought....meh.
You are correct ....imagine the disappointment with my first store bought upper in 6mm ARC. With the Areo Precision upper and a BA barrel with 108 eldm match ammo it shot 2.5" 5 shot groups. Disappointed with the terrible accuracy, I built another with a Proof Research barrel and fired them on the same day with the same ammo. The Proof barrels first 5 shot group was 1/2"....the Areo precision upper shot the same 2.5" group at 100 yds.
Bought another 6mm ARC Proof Research barrel and discarded the Blastic Advantage barrel and rebuilt the Areo upper. It also shoots groups in the .4" to .5" for 5 shots.
So I like it for the accuracy, with Proof barrels.
Fact is, for me, the 6mm ARC would be history if it weren't for the accuracy of the Proof barrels...making it fun to shoot.

Long thread, I'm sorry if this is already somewhere in here.
I'm going to be sitting down to start loading after I jus got my 18"AR barrel. 62gn eldvt. Looking to load AR Comp or H4895. Any point me in the direction, or know, where to find a good place for starting/max loads?

The Hornady online is a great starting place.
Thank you. I should've looked there. Just knew my book was way too old. This should get me there.
Probably going to be somewhere between 26 and 29gr. In fact, pretty much all powders in the 8208/Varget/TAC range are going to be somewhere between 26 and 29gr. Any variation in there will be specific to your bullet weight, barrel, and gas/ buffer combo. Just start low and work up.
ELDVT isn't in the QL library, 65JLK is pretty close though.

I have no issues shooting 73-77g pills out of my 223's. They shoot better out of my ARC Bolt that my 223 Bolt. They carry more speed and shoot a little better. I think a load for my 22 ARC was a little easier to get to than my 223 as well.
22 ARC is 22" long & my 223 is 20".
I realize this is different than an AR in every way.
