Suppressors Copper coated 22 LR bullets for shooting Suppressed..subsonic?

[Baer45]

I am trying not to shoot exposed lead ammo through my suppresors but it is hard to find copper or copper coated subsonic rounds. What is the best subsonic ammo for a suppressed 22?

i like the CCI Segmented HP subsonic. Not sure it(or any other coated 22) is much cleaner than the regular CCI SV though. My guess would be that they are all pretty much the same.
