What was the ammunition used?
Good question: Federal Bulk. Unfortunately I did not think to take any other ammo. Next time I will try a variety of ammo.

I have a dedicated .22 upper from CMMG bought from Questar with Black Dog mags. Everything works flawlessly except in the winter; more stoppages. Great system for training on cheaper caliber, only difference is no bolt hold open.
While it's a bit fussy to set up, the Bolt Hold Open Adapter (BHOA) works fine. You get a reduced strength spring with it which I have never used.
About 5-6 years ago I purchased a Tactical Solutions AR-22 dedicated upper with a number of Black Dog magazines. This combination was a match made in heaven, until the springs on the dedicated upper required replacement. I tried for over a year to get the Tactical Solutions Maintenence kit for the AR-22 with absolutely no luck at all in both Canada and the United States.
Last year, I decided to just buy a new kit and go the CMMG Echo kit. With the kit came one magazine, when I fitted it into my AR's mag well, it took two adult males to remove the mag from the gun. Luckily only the magazine was the only part of the kit that is garbage. With my original Black Dog Magazines the CMMG kit cranks out the rounds flawlessly all day long.

I hope you have better luck with yours, than I am having. I tried various different ammo on Sunday morning, and nothing was running without multiple failures from the CMMG mag even without the BHOA installed. While the bolt hold open feature would be nice, I am considering selling the 2 CMMG mags and BHOA if I can't get them to run properly. Also I can't load more than 10-12 rounds into the mag.
Please let me know how yours work and pass on any useful hints

I don't know what ammo you are trying or exactly what mags you have but I had similar problems last year. Eventually I concluded that the mags choked on the longer OAL cartridges. I finally settled on Federal bulk hollow point. The HP's are slightly shorter in OAL and worked well. My problems were with the Evolution or Revolution magazines with steel feed lips.
I no longer have those magazines or the upper. I did buy a conversion bolt this year and the older grey plastic mags with plastic lips. I have not had any problems with these magazines and have tried several ammos without failure. I use the same ammo in my .22 pistol.

Well I went with a 597 vtr. It accepts AR buttstock, pistol grip and free float rail. So you can swap what you have on your AR back n forth and train with the same stuff. It is also non restricted so you can bring it out in the bush. Heavy barrel, upgraded extractor and I feed it winchester wildcat 555 all day long.

I'm going to have to change the spring to make the BHOA work. Do you have the same mags as me? I fit 23 in one yesterday, I gave up on the last 2 because it was too hard on my fingertips. Have you tried pressing down on the bullet seated in the mag and then pushing another one in? That's how I squeezed all those rounds in there.
I have Winchester M22, Federal Bulk 36 gr, Minimags, Remington golden bullets, Winchester 555 packs. I'll see what works. The followers on these black CMMG mags are plastic.
I have 2 of the same mags that you have. However one is still in the original packaging as I may be trying to return it or sell it soon. I could probably force more rounds into my mag, but the resistance is very strong and I suspect that they would not feed properly. I don't want to introduce any more variables at this stage. I am loading them while pressing down hard on the previous round. If I can even get the half full mags to work with the BHOA and upper I will be happy. I suspect that loading issues will improve over time as the mag and spring get broken in.
I will be bringing it out to the range this weekend. If the upper works fine without the BHOA actuator I won't #### around with it very long. Please wait before tossing your mags ; )
My 2cents, I got a bushmaster carbon-15 22lr works good most days had some mag issues off the hop but now that it's broke in I only have issues when I try to squeez an extra round into it, I'm also a clean freak when it comes to guns and when u let the bushmaster get to dirty (500+rnds) then it gets cranky. All in all $500 gun $75 ncstar un magnified red dot and it'll hit torso sized gongs at 100 easy... It's defiantly not a 200/300M gun, In short I'd buy it again
Back from the range. I shot about 1000 rounds total of various makes in the following order :
CCI Minimags 40 gr and 36 HP gr x 200 = 100%
Federal bulk champion 36gr HP x 350 = Very reliable at first but hiccups started at the 500 round mark
Remington thunderbolts 40 gr x 50 = 100%. I was astonished. They even cycled my Kimber too.
Remington golden bullets 36 gr HP x 50 = 100%. Surprised.
Winchester M22 40 gr x 250 = These were reliable at first but at the end 4 spent cases got stuck in my AR's chamber and also happened consistently in my Kimber pistol, had to use a rod to get them out. As the round count went higher these were worse and worse. When I had had enough of them, I switched back to Federal bulk and the problems were fewer between and less obnoxious to clear.
Guns were clean when I started and conditioned and lubed with FireClean. I did not stop to clean them at any time during the shooting session. My 3 mags worked with no problems. At first, the mags were loaded with only 10 rounds and I kept increasing the load until I was loading about 20 every time. Most stoppages were near the end of my session and were consistently failure to ejects as the guns were getting dirtier.
I'm going to stock up on anything that CCI makes, Federal bulk, and even golden bullets (and they work very well in my Kimber Rimfire which is notoriously finicky with anything other than minimags). Winchester M22 is dirty and sticks in hot chambers. I will not buy these again. They are stamped ''SUPER X'' on the bottom which leads me to believe they are just that packaged in a box with an AR on it.
The BHOA doesn't work on the last round because I haven't changed the SR-15's spring. I won't be doing that. I still use the BHOA because I can lock the bolt back manually to clear jams and everything. I didn't use the CMMG 22LR handle, I used my BCM ambi. As far as I can tell, the .22 handle might have prevented 1 strange jam that I had. Most jams were failure to ejects because of weak rounds / dirty guns.
I was shooting at about 15m and mostly double taps and mag dumps so I can't attest to how accurate this rig is. I'll try that another time. I wanted to break it in real good and see what ammo it enjoys.
PS : I'll take your mags if you don't want them !
