Personally I prefer CCI Mini-Mags.
I think Federal auto-match is not very good.
Sure as hell no Winchester white box or golden bullets.

My bolt gun will eat anything but my semi-autos are most consistent with the Mini-Mags.

Any other recommendations for semi-autos ?

I've got a CMMG .22 conversion kit for my AR and ran through 1025 rounds of Blazer with zero malfunctions.  Conversely in bought a bulk pack of Walmart Winchester M22 and after 150 rounds it had leaded the barrel so badly that I couldn't hit a 8" target at 10 yards.  (normal groups are 5" at 25 yards)

My SR22 pistol will eat anything for 200-400 rounds and then it starts to have extraction problems with the worst so far being Golden Bullets.

For reliability, CCI AR-Tactical and Armscor I find are solid. 2nd for the Blazers, either 38gr or 40gr, great reliability and typically cheap in bulk.

Aguila and CCI Standard velocity. Shoots well through my CLE 22 upper (Douglas barrel), Nelson .22 conversion for 1911 and not so bad with a Remington 40x.
Wolf Target and SK Standard (rumored to be the same thing - just rebranded) works the bestest in my semi autos. Best accuracy and functioning but more expensive.

CCI Minimag is my favorite for any gun. I’ve tried some Federal high velocity stuff and it was pretty good, but tougher to find in stock. I’ve had good experiences with the Blazer black/grey box as well.

I avoid Federal Champion in the blue box. That stuff is absolute crap in anything semi-auto. I had a couple of bricks of that and tried to give it away and people wouldn’t take it. It was that bad.

I don’t have much experience in 22s, but been meaning to shoot them more and pick up a 22 rifle. I have a bunch of old 22 amp that my dad left me. Was hoping to shoot them up and share with Inspector (my 22 guru), but then life happened. 😢

I think I have probably tried every brand/product of 22 available on the island. One day about 7 years ago, I went to every LGS and bought every brand I didn’t already have in stock and tried them all out in my semis and bolt guns. Mind you it took me 2 years to finish the project! 

There are a lot of good and a lot of not so good 22 ammo. After all of my testing the old adage that whatever shoots best in your 22 is still the truth. And to find it you need to sit down with your semis and a shit load of 22 and test test test.

With that said I found, generally speaking, that it was beneficial for me to standardize on a few brands/types in order to keep my sanity. I own a lot of different 22’s and they all shoot better with different ammo. And that is too much for me to keep track of. And too expensive and takes up too much room. In my testing I found Mini Mags and Blazer to be the hands down high velocity champs. They ran in every semi I could shoot it in. I have some semis that I can only shoot standard velocity in. They are accurate, reliable and clean burning. I standardized on Blazer due to it being a little cheaper. But I always keep a few boxes of Mini Mags in reserve just in case I get a semi that doesn’t work with Blazers. It has never occurred. BTW, Blazers also work in my 22 conversion for my Glock. They recommended only Mini Mags. I also found that Aguila high velocity came in third and worked pretty good but is not as consistent in the accuracy dept. As far as standard velocity is concerned I found CCI SV is the best and most consistent. However lately I have been finding some with too much lube on them and that can cause feeding issues in my picky semis. Aguila SV is also very good but I found a flyer out of ever 10-20 rounds. I use CCI SV ammo for target practice and in my semis that can only shoot SV as CCI SV is usually very consistent. For competition I usually use SK Rifle Match and SK Pistol Match. However, it is quite expensive.

My standards are:
CCI Blazer/Mini Mags
CCI SV
SK Rifle Match
SK Pistol Match

Your guns might tell you differently.

I only recently acquired a .22 semi-auto.  Basic stock Ruger 10/22 stainless.  Haven't shot it enough to figure which ammo is best but as far as feeding issues all the ammo I tried cycled reliably.  But I only tried Federal blue box, Thunderbolts, and CCI mini-mags and standard velocity.

I ordered a case of Aguila copper plated HV ammo through Kaleo Arms and will see how that works.

I've had a SA Western Marshall .22 LR revolver since 1980 and only recently started shooting it again.  Of course there are no feeding problems but I can't seem to hit anything consistently.  I believe my old eyes are a big part of the reason, I just shake my head as to why I can't shoot out the bullseye and instead make holes all over the target face, even devastating the target frame, lol!!

I've had the revolver safely stored for over 30 years but maybe I didn't maintain it well.  Maybe the barrel is pitted?

For my SR22 pistol and 10/22, I like mini mags and Federal Game-Shok 40gr (#710). Both reliable and consistent.

It’s hard to tell what the real problem is without seeing the gun up close and without watching you shoot it. I have one gun I cannot shoot for shit. I took it out on Saturday and watched my nephew shoot straight as an arrow with it. I pick it up and I can’t hit an 8” target at 21’. I have come to the conclusion That I cannot see the stock sights very well. I have bad eyes and all my guns I have changed out the sights to something I can see/use. Except this gun. Once I get better sights on it I should be able to hit something with it. Another thing to look for is a nick on the crown of the barrel. A nick would also cause the problem you are seeing.

Thanks for the advice!   I'll check the crown.  Maybe there is a nick.  Or maybe I just need to get into the groove.  I haven't shot for over 30 years and only recently started again since I retired last year.  Since then I've only been to the pistol range3 times and rifle about the same.

Getting old sucks sometimes. My eyesight just gets worse year after year. Fortunately, we have capitalism that creates more and better sights for us to replace when we have a problem seeing sights and targets. The sights on my gun that I can’t hit with are so old the white dots have yellowed and are harder for me to see. Plus it is a 2 dot sight system and not a good 3 dot that I prefer.

I've found Blazers and Minimags work in everything.  Reports on the internet say that Blazers are the same as minimags without the copper coating and packaging.

Automag and thunderbolts used to misfire, about 10%, in a Glock Advantage Arms conversion when it was new.  They work perfectly fine now after running 500 blazers through the conversion.

Ran several hundred rounds of CCI Mini-Mags through an Advantage Arms conversion on a Polymer80/G19. No hiccups, light strikes, FTF or FTE. That was the break in for it, so could only imagine it would get better

Always depends on the firearm.

My Ruger 22/45 Lite eats anything I feed it.  It has more of a rifle-style bolt action than a pistol slide action.  All my Ruger 10/22 rifles cycle flawlessly with anything, too.  If I have problems, it's with QA not weeding out the poorly manufactured rounds -- loose projectiles and light loads mostly.

I have one GSG/Sig Sauer 1911 that says right on the slide to use high velocity ammo, or else the slide may not (will not?) have the energy necessary to fully eject and chamber as it should.

Sure enough, anything with less than 1100+ FPS is hit-or-miss when trying to cycle.

Those with the Advantage arms glock conversion, did any of you try cci velocitor?  I know they don't mention it in the list but they do mention not to use hyper velocity ammo. Just wondering if these will cycle better...didnt try my conversion out yet

I am partial to federal GMM 40 grain lead HV
Or cci mini mag
Been watching some 22Plinkster videos lately and he likes 40 grain lead SV in his Volquartzen firearms. He says saves the accuracy of the barrel longer vs copper plated
I'm going to try that out next

I used Winchester Hyper X and Remington Vipers, no issues. Still, if the manufacturer says don’t do it, I defer to their wisdom. My go-tos are CCI Mini Mags and Blazer Gray Box

As great as CCI Mini Mags are for me, CCI SV has always been a bit more accurate for me past about 50 yards. I think there is something to the theory of HV bullets becoming a little unstable as they pass from supersonic to subsonic. I have tested Mini Mags at 50 and 100 and CCI SV beats it every time at 100. But at 50 it is much much closer. As far as copper washed/plated I always felt they could be a little more accurate than straight lead (Based on my experience with centerfire cartridges) but I have not seen this with any 22 ammo. As a matter of fact all of the most accurate ammo like SK, Eley, Lapua, etc. use straight lead.

I have tried a bunch of different ammo in my AA Glock 17 conversion. Most had some issue or another. I have never tried the two you mentioned. But the ones you mentioned are your go-tos are my go-tos as well.
