Be prepared for a high level of frustration. Subsonic rounds will not reliably cycle a semi-auto. This warning appears on the ammo box on most brands and in most ammo company's description of the ammo.
Research is a wonderful thing.

Sounds like sloppy research to me....subs work fine in mine

Just last night I watched a Youtube video of guys shooting a suppressed 15-22 with subsonic ammo. They didn't mention any FTFs and didn't have any on the video itself. Give it a try and let us know how it runs.
Standard Velocity or 22-Quiets? Standard Velocity are subsonic and work well in my 15-22. Quiets are definitely quieter than even Standard Velocity, but they don't work reliably for me.
Again, might depend which subsonics they were using in the video. Standard Velocity and 22-Quiet are different as far as CCI goes. Not sure about other brands offerings. With a suppressor there should be a little extra backpressure, maybe enough to run 22-Quiet. At least that is my hopes for when my stamp finally comes back. I could live with CCI standard Velocity (it works well in my 15-22 now), but I hope Quiets work better with the suppressor.

Standard velocity and subsonic rounds are not the same thing. Standard velocity is pretty reliable; subsonics are not. Correct terminology is important.
Whether or not standard velocity is subsonic depends both upon barrel length and barometric conditions. Standard velocity is generally not subsonic in rifle length barrels.
There are a few existing threads discussing the subject.

True, although at 1070 FPS CCI Standard Velocity generally is subsonic. At 710 FPS the CCI Quiet-22 is definitely subsonic.

Not sloppy research, lots of experience shooting the stuff over the years.

And 710 fps won't cycle most semi-autos.

They are 1050fps. 22 lr hp subsonic
They'll hopefully work fine at 1050 FPS. They work great in mine.

S&W 15-22 op manual says no subs. Just saying

The manual also doesn't say anything about the crisis were in, find what you can

CCI Subsonics cycle in mine... CCI Quiets don't... Just my 2 cents on how they work in my rifle...
Nope 22 quiets won't cycle a 15-22 with a can on it. I tried, it's really fun though. They however are super quiet out of my savage FV-SR with the can on it.

1,050 fps is not subsonic velocity. It's standard velocity. True subsonic rounds are under 800 fps.
Sound barrier is right around 1100 fps, so standard velocity does have the potential to be subsonic...but uniformity of the load and atmospheric conditions can change that. Standard velocity will generally be subsonic where I am. And it will cycle the action, which is nice.

The potential for standard to be subsonic is much greater in a pistol, where the rounds does not develop maximum velocity. Not so much in rifle-length barrels.
And, as you say, atmospheric conditions play a part in that.

I put about 10 rounds of this stuff thru mine once
and there were only 2 of the 10 that did not cycle the bolt.

I've put tens of thousands of CCI Standard Velocity (rated at 1070fps) through my 15-22 and Sig522 using a suppressor. Never have I heard the telltale "crack" of a round going supersonic. On the other hand, when I tried Remington Subsonic (rated at 1050fps) they regularly went supersonic or either didn't cycle the action.
If you are looking for ammo that stays subsonic and will reliably cycle, I don't think you'll find better than CCI SV.
Keep a close eye on sgammo. They have been getting CCI SV in stock every couple weeks.

same with me, all subsonics work great with mine and a Pilot II. Have so many through it had to have the baffles blasted last week since it weighed about 2 pounds!!! was still quiet though. that is from shooting jack rabbits in the orange groves...big fun! Also quail, shoot one in the head, his buddy comes to check him out, he's done for also and does not spook the covey. they stay put and you just plink them away.
i even shoot them in my garage and no one hears anything except the bolt and the bullet hitting the bullet trap.

Even without the suppressor the CCI Standard Velocity should stay subsonic. The original reason I brought up the differences between CCI Standard Velocity and CCI Quiet is because in all the literature I've read, CCI never uses the word subsonic. So the original post that CCI subsonic was all that was available could have meant either. Standard Velocity which is usually subsonic, and Quiet which should always be subsonic. There are other brands such as Remington that actually use the word subsonic as part of their nomenclature.

Gee, no supersonic crack on a suppressed firearm? Imagine that! That, in and of itself, does not make standard velocity ammo subsonic.

As they should.

It says so right on the box "sub-sonic 22 lr hp 40 grain"...

I've only had my 15-22 a few weeks & can read just fine... even though I am from Mississippi. I understand S&W doesn't recommend using sub-sonic ammo, however my plans are to shoot mainly suppressed once my stamp comes in. I decided to go ahead & give the gun a try using CCI Sub-Sonics and was actually amazed that the ammo worked flawlessly. Several hundred rounds with not an issue & they did plenty of damage to left over pumpkins.
I am a rookie with this gun (have a Stag 2T) but would suggest getting all this ammo you can find. If it doesn't work for you, I would think others would gladly relieve you of your burden.

Huh? Don't get your point.
CCI Standard Velocity stays subsonic shooting in my rifle because it does, period. The suppressor doesn't make the bullet subsonic. What a suppressor does is make it OBVIOUS to the shooter when a bullet does go supersonic because there is very little muzzle report to disguise the supersonic 'crack'. If I was to shoot HV ammo in my rifle the suppressor would still do it's job of reducing muzzle report, but the supersonic crack would be so annoying it would hardly be worth it.
On the other hand, I can shoot HV ammo in my MKIII with a 4'' barrel and the bullet will stay subsonic. With my 5'' Ruger the HV ammo goes supersonic. This is why I was specific about what guns I was using it in.
Temperature and altitude have an affect, but those are variables that are a bit beyond the scope of this thread.
