20" Craddock RTR 1:7"
29.5gr CFE223 75 ELDM @ 2.240 = 2950fps
.6" for 5rds, .6" for 5rds, .74" for 5rds, .63" for 5rds, and .76" for 5rds. Two groups would've been .42" and .34" except for first and last round fliers. This load shot 3030 ft per second at about 1.5" in a 22" Baldwin gun works 22 Grendel barrel.
26gr 8208, 75 ELDM @ 2.280 = 2899fps
most accurate at .37" for 5rds
26.5gr 8208, 75 ELDM @ 2.280 = 2950fps
.46" for 5rds
27gr 8208, 75 ELDM @ 2.280 = 2999fps
least accurate at .74" for 5rds and showing pressure
Used my old 22 Grendel brass and just ran it through the new Lee 22 ARC dies. I still had 60 rounds of 22 Grendel(CFE load) loaded up. I shot 30rds of it to help get zeroed, set the gas block, and run some rounds through thru the barrel before testing the 8208 loads. Everything functions fine but headspace on the 22G brass and ammo was 1.174 and fired brass from the Craddock 22ARC is 1.181. Same BCG and rifle parts; just pulled the 22G barrel and replaced with the 22A barrel. Used the Hornady headspace comparator and .400" insert to measure the shoulders. I'm looking forward to trying some TAC and maybe even some StaBall 6.5.
Hoping I can get sub .5" consistently at 3000fps plus once the barrel speeds up and brass is sized correctly. Hopefully TAC can get me there. If it doesn't work out, I at least have 8208 at mid 2900s was excellent accuracy.

I'm going to reshoot it tomorrow. I put some side weights on the foreend and the mlok screws caused some fliers. Had to file them down. Definitely showed some promise
No luck today. I loaded the 75's at 2.250" and shot some 1 - 1.8" groups. Definitely got the velocity I wanted but accuracy lacked. I will try some more seating depths but as of now TAC doesn't look promising. Which is a shame bc I like that powder and have a lot of it. I might try Varget, 6.5 StaBall, or N150 next.
Try the 75 eldm @ 2.30 OAL. Mine didn't tighten up until I got down to 556 velocities.
TAC still isn't doing great for me. 2.230" definitely opens up. 2.240" seems to be the sweet spot. I shot the last 10rds of 22 Grendel ammo I had loaded up. 29.5gr CFE223, 75ELDM at 2.240. Still shoots good with that load. Think I'm done with TAC.
I cut little boxes out of the paper bc I ran out of pasters. There's two rounds inside the little cutout in group #2.

How many gr of CFE to get the 80 to 3100? What about the 53?
I'm testing the 62gr ELD-VT. Factory ammo is running 3200 from my 20" .
Curious to see your results on how yhe factory ammo groups. I used to have a 22 grendel and sold it out of necessity at the time. Thinking it might be time to get back into one. It would be great to not have to do all the brass prep and handload again.
I have the 75 eldm and 88eldm factory ammo. I can test it sometime soon.
I have stocked up on all the 22ARC components waiting for a factory bolt gun to hit the market. I have a fair amount of CFE223 from my 556 loads but was wondering if anyone has tested the waters with Reloder TS 15.5. It sits only one ranking slower than CFE223 and well within the range of powders in the published load data for the 22ARC.
I have used Reloder 16 for years in my 6.5C and 243Win loads with great results. Both 15.5 and 16 are touted as very temp insensitive, whereas I have read several posts concerned with CFE223's temp sensitivity. Thank you in advance for any words of wisdom from this experienced group.
P.S. My primary expectation is to shoot coyotes with the 62gr ELD-VT, but possibly move up to the 80gr ELD-X for hogs and whitetail if the opportunity presents itself.

‘16 is great in my .22BR w/88’s. I suppose it would be the same in the Arc.
I couldn’t find a node I liked with ‘16 and 80.5’s, which led me to think I needed something a tic faster with lighter bullets.
LVR is magnificent with 75’s, but yes, it is a bit temp sensitive.
With 62’s, I’d try StaBall Match. A friends .223AI love it with 69SMK’s.

Thanks for the info. I would love to use RL16 as I have about 12lbs of it, but the charts show H4350 as compressed, so RL16 would likely be the same. Your logic is what made me think of RL15.5 since it is a little bit faster. Thanks again.
I am pretty sure RL16 takes up a lot more space than 4350 in a case. I'm betting it would be too slow combined with it's bulk for the ARC case
Going thru old supply of 3 gun bullets. Came across 1000 rounds of sierra 69 gr BTHP match. Did some load work up with the Hornady 62 gr and found my barrel likes that 3260 area with. 30.6 of Lever.. Hornady load data for their 68 gr BTHP has max charge of 29.5 of Lever. Do you think this is a good max reference for the 69 gr. for load development.
Got my new Ruger American Ranch 22ARC to the range yesterday for some initial powder tests with the Hornady 62gr ELD-VT. CFE223, H335, Varget and Reloder15.5. Looks like my limits are in the 3100-3200 fps range with the 16" barrel. Started to see some primer cratering at the top end, but no flattening of the primer, ejector marks or stiff bolt lift. My firing pin hole may just be a little too big. Using CCI450's so it is not a soft primer issue.
Reloder 15.5 was too slow at 30.0gr. (100% filled case), only got up to 2900fps. It may be good for heavier bullets like the 80gr ELDX though. The gun, however, would not feed for sh**. It's going back to Ruger on an RMA to check the feed ramp or something. It is not field ready. Disappointing since I have been waiting for this rifle to make it to market for months.

Since I had so many powders and range of charge weights, I only did one round per charge so the POI moved around quite a bit.
Now that I have a much smaller window to consider, I will do progressive 3 shot groups and chart the POI changes.
Based on more research, I think I am going to introduce Win Stabal Match to the mix. I am really looking for temperature stability and low SD/ES.
Now I will just have to wait to get the rifle back from Ruger due to the feeding issues before I can do any more load development.
What velocities are you getting? I really want to do another MK12 but in 22 ARC. Even gave thought to just swapping barrel and bolt on my MK12.
18" craddock RTR
Yes tried RL16, Staball Match, Staball 6.5, TAC, cfe223, n540....
Only rl16 was close on es/SD. I'm fine with the velo. My main issue is the chamber is wholly shit long. Have to create a false shoulder of 12k on new brass. Kinda a pain in the ass, but works ok.
Since RL16 was a close contender. I wonder how it would compare to H4350 in a temp stability test. 5 shots at ambient summer temps and 5 shots out of a cooler. In other calibers, I have found RL16 to be more stable than most. Staball Match is also touted as being very temp stable (no experience with it yet though). When I hunt coyotes, it could be 33 or 103 degrees.
I've found RL16 to be very temp stable, just can't get enough in the arc case to get any velo. Staball match has been very good temp wise in 556 loads with 77 smk and 55 blitz for me.
I admit to not being a big gas gun guy, but the instability of cfe223 and Lever are a nogo for my uses.
Also of note is that my es on 5 shots with 16 and 80 vld was 4. But only 2600 fps.
Another option is RL15.5, I was able to get 30.0gr in the case but with the 62gr ELD-VT is only at 2,900. Still might not get you the velocity you are looking for. RL15.5 (not RL15) has the same temp stability as 16 but is a bit faster. If Staball Match does not work for me in the 62gr, I will move over to AR-Comp, supposed to be another temp stable powder from Alliant. I sure wish you could get 1/4lb samples and not drop $50-75 just to put it on the shelf for perpetuity.
Interesting, I’ve been playing with n550 and 88s, so I was just wanting to feel out other people’s results with similar set ups
I was in sportsman’s today and saw a 16” 22 ARC Ruger American Gen 2.
Not a top end gun, but for $575, might be worth it just to try the 22 arc.

Starline has no plans to make 22 ARC brass.
This is from an email I got from them in April:
"We are very limited in new product development due to the volume of orders for most of our production lines at this time. Once things slow down a little bit, we will consider adding new calibers to our lineup, although this is not a caliber we are currently considering. I apologize for the inconvenience."
The starline 6.5 grendel works awesome for 22 arc. Best brass i have found for the arc so far. Hornady brass is decent but not as good as starline. And the lapua 6.5 grendel brass sucks
What is your method for necking down? Do you do it in 2 steps? Use bushings, or regular dies?
I use one shot or graphite. One step in a hornady 22 arc die. I've done 4 hundred so far and zero issues. Make sure to chamfer in and out well and you shouldn't have problems.
I use regular hornady dies and royals case lube. One pass and done. Works perfectly and sizes easily. Royals case lube is the best case lube bar none.
The Starline 6.5G are a simple one-step process but don't be surprised if you have to neck turn down a mil or two. All of mine started out at 15 mils so by the time you insert the bullet you are at about 0.254, which is beyond spec. I turned mine down to about .01375, once it is fired, a new projectile barely slips in the opening.
I am not a fan of any of the Hornady brass. I only use it in hunting loads that will end up lost in the weeds.
Additionally, several people above have said they have difficulty getting any neck tension with Hornady brass since they seem to run around 11 mils and the Hornady dies wont size them down enough without a bushing.

Has anyone ran a 22 arc profile through quickload?
Specifically wondering about the 75-88eld. I feel like because it’s so new there are a lot of powders out there that would work, but there’s no load data yet. Guess I’m wondering what QL would spit out compared to what load data we currently have access to

Picked up a Ruger American 22ARC 20” not long ago and have put about 200rounds through it so far.
Chrono results with Hornady factory ammo 10 shot strings
62s 3150fps
75s 2930fps
88s 2688fps
10shot group with the 62s was 1.5”
2 10 shot groups with the 75s were 1.0” & 1.3”
10 shot group with 88s was 0.9”
Wind was 8-12mph and switching while shooting.

Running the 10rd 6.5grendel dura mag it came with feeding has been smooth and flawless.
Base of the muzzle threading job is shit and the hellfire muzzle adapter is def not making full contact. Will get that fixed but it’s still shooting decent.
3 position saftey is nice. Action runs pretty smooth with some oil and bolt lift after being fired is not bad after 100 rounds or so. Put a 2lb trigger spring in and got a anarchy bolt handle although the factory bolt handle isn’t bad with the round knob.
Shot the 88s and 75s side by side 2 different days at 100 & 750yards 40 or 50 rounds total to see which one had less wind drift. Shot them alternating in the mag a 750 on a 3’x3’ plate. They seemed to have the exact same wind hold at 2688 vs 2930 which is what my applied ballistics solver predicted.
Hoping I will have a plinking load with the 80s around 2930fps
Also going to test some 95smks for the heck of it with accurate 2520 & BL-C2
With a March 1.5-15x42 (23oz) & Tbac ultra 5 it’s 8.7lbs

No. Published Hornady 22ARC bolt gun Load data shows 28.5gr of varget as a max load, 3000fps, 24in, Coal 2.250”, 80gr eld-m. It states pressure is between 60-62K
Below is the max charge tested 30.6gr of varget where I started to see visual pressure signs That was 3109fps in a 20” barrel with the 80gr ELD Coal 2.235”
