My favorite 22...
A cz 452 is a solid choice. I think the current 457 or whatever is of simular quality, just no experience with them.
The ruger rimfire precision is my current 22 supressor host. I don't pack it squirrel hunting per say, I do take it to the feed lot and smack pigeons out to about 200 yds with it.
A savage 93 or I think their b series would be another solid choice.
Tikka, anshutz, volquartsen, and others make really nice 22's. I just view them as more of a target gun than a toss in the truck and run a muck for critters 22.
