I've been thinking about a .22 for target shooting. I know everyone likes the 10/22 but I am thinking bolt action (help keep the boys from going through ammo like candy). I kind of like the Ruger American but I don't think there are many upgrades out there. I like the looks of the CZ 455 and there are many models to choose from. There is even the package with the .17HMR barrel included. Just looking for any opinions or experience with either rifle.
