CCI Quiet
Do mini-mags stay subsonic?
Most regular bulk 22lr will stay subsonic in a pistol.
Quiets are good for anything except a semi-auto. They will not cycle a semi-auto. Really, they are kind of a waste with a suppressor though, because they are really quiet without one. I've mainly used them in a cricket with smaller kids so they could shoot without hearing protection.
For rifles, I will use subsonic ammo. CCI Standard Velocity is one of the best.
^^^^^^^^
All 22lr ammo is subsonic in pistol length. Can't remember at what length it isn't, but it's on youtube somewhere. Just get a (relatively) clean ammo especially if you can't clean your can. I like CCI the best myself. Federal is also good for me.
Be careful bandying words like "all" with the incredible variety of .22 ammo and guns.
That is expensive.
That is my go-to for subsonic generally. Aguila Subsonic has been another less expensive choice.Agreed.
This is also sub-sonic (barely) but at half the cost:
