I recently traded in the CZ.22 for the CZ.17HMR, it is a seriously flat round, also got Ruger .220 Swift and a few Shotguns, one good one and one for belting vermin.
The dogs go mental if I walk out with one coz they know whats ahead, if the dogs had a choice they would go shooting every day, you can almost see them smiling when coming back with a retrieve. One of the funniest things is when the two labs are out with me and they both get on to the same retrieve, both running back together, both holding a rabbit. All the dogs want to do is please. Mind you if I had a choice I'd go shooting every day aswell.
