Iff'n it was me:
1. Use CCI Standard Velocity as your "go to" round if you want to avoid the supersonic crack. It's subsonic, and has enough power to cycle every semi-auto I've tried it in. It seems to be the standard in the silencer community (at least in my neck of the woods).
2. Maybe you can find them in your area (I've yet to see any in the wild), but the Federal Suppressor 22 ammo goes CCI Standard Velocity one better by coming in a copper plated round. The copper plating helps keep your silencer cleaner.
3. If you don't mind the supersonic crack, go with any speed in a copper plated round in order to keep your silencer cleaner. I have no particular favorite, but I do prefer Federal and don't bother with Remington.
4. If you're going to shoot thru a pistol, stick with the supersonic, copper plated rounds. Cleaner due to the copper plating, and you will lose enough velocity thru a shorter barrel that those supersonic rounds will be subsonic.
Bottom line...I use CCI Standard Velocity thru my rifles only for times when I want the ultimate quiet.
Any other time, I'm using a copper plated round - may be supersonic out of my rifle (but I'm at the range, etc.) and is not supersonic thru a short barrel as a pistol.
It's usually easier / cheaper to find supersonic copper plated rounds than it is CCI Standard Velocity.
And finally, don't overpay!
The 22 shortage is over, although prices are still on the high side and there are certain regions that apparently haven't caught up.
At my local shop, bricks of CCI Standard Velocity run $29.99, $36.99, $39.99, depending on what supplier he gets them from.
He has tons of other stuff cheaper (those supersonic, plated rounds).
