Ruger 10/22
Oh, go with a few million other users and get the 10/22.
Yep, you can get more accurate, but it's hard to find one more reliable. You can also play with it all day long - have a look at Brownell's catalog for the zillion of trigger toys, extended mags, flash hiders, custom stocks, mount systems, all that, if you like to tinker and customize.
And, since there's more 10/22s in circulation than any other 22 on the planet, if you don't like it, you can trade it to somebody who wants one.
I have several and have bought them for my kids and friends. I shot my first one back in the 70's and have been shooting them ever since.
The Ruger is accurate enough for squirrel hunting and whatnot. If you like to plink, the mags are really handy and it's a reliable feeder. Since prices for aftermarket mags are low, you can buy a handful of mags and get in a lot of play time at the range without breaking the bank. If you want a little carbine to play with, they offer that configuration... or if you want a heavy barrel target model, they have THAT. And you can customize to your heart's content.
You can certainly argue the merits of other 22s, but there's reasons the 10/22 is the most popular one on today's market. The little Ruger does so well in its niche that the others are just that - "others."
If you really want a boltgun, the 77/22 by Ruger's a nice gun. I've heard a lot of folks who like their CZ, but I haven't owned one. My 77/22 uses the same 10/22 mags, and again, custom parts are available (like triggers) for the 77/22. In general, Rugers are very hard to beat for value and they're CERTAINLY rugged firearms.
