All I could find today

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.

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. :D

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.

The boxes of CCI Standard Velocity and Quiet 22 don't say subsonic on them anywhere...

Exactly, the suppressor has negligible affect on the muzzle velocity and wouldn't stop the supersonic crack of a high velocity projectile. The one way a high velocity round with the suppressor makes sense is because it still reduces the muzzle blast, which I believe makes it hearing safe without ear protection (never at the range where there might be other shooters with loud guns though).

Temperature has the greatest affect on the speed at which the bullet would become supersonic. Altitude has air density and pressure affects that essentially cancel each other out. But in the sense that at different altitudes you may have a different temperature, that would have an affect.

Like these ones?

Interesting, I had never seen those before. Probably because I don't usually look for hollow points. That and locally we don't have a huge selection. Most places that carry CCI only carry Mini-Mags for some reason. Actually, checking the CCI web site to see all the .22 they offer, they have some pretty cool loads. Thanks for pointing that out to me :)

I've got some CCI Subs around here someplace... oh here's some . I'll take a pic of CCI SV and SS.

As you can see, there's not but 20fps difference. I don't use the SS unless I'm on critter patrol. :D

Telero... that's because you don't have a box of subsonic... you have a box of standard velocity and quiets... not subsonic...:)

Exactly, they just both happen to also be subsonic. Around here, the only box I've ever seen that actually has the word subsonic is the Remington. I guess I need to start buying my CCI online.

Remington... no no no... bad bad bad... :D

These are both rated 1050fps. They will regularly go supersonic or fail to cycle the rifle.
