Thanks guys for the recommendation.
I would love to have a CZ457 but I just bought a new 10/22 a few weeks ago to see if I like the sport. (Ended up loving it!) Is it that much of an upgrade going from a $430 10/22 to a $900 CZ457?
I'm kind of bothered by the idea of selling the gun soon after buying it. And I probably don't need two rimfires.
Use the 10/22 if you already have it.
You can always upgrade to a new in the future if you outgrow it. You can also upgrade the 10/22 - lots of aftermarket support for the 10/22 and precision upgrades.
Enjoy.
