Missing the obvious?
Just wondering why no-one mentions the Ruger 10/22?
The O.P. States he'll consider any action, so why not the most flexible and reliable .22 platform on the market?
Nothing against the CZ bandwagon you have going, but looking at price, and superwide availability of options the 10/22 is the way to go. $179 at most retailers new. Wal-Mart version (black synthetic stock) is often less.
