Fella's;
C'mon, Juliet Tango specifically asked about semi-auto.22 rifles. The Savage MKII is a bolt gun. I've also owned one & it's a damn good rifle, but it isn't on-target in this thread.
I am surprised that you found a CZ semi .22 in the same price range as the Marlins & Rugers. Care to inform us curious folk where you ran across that?
Any/all of them can be made more accurate if the first thing you do is test ammo. Twenty-two's are notoriously picky about what they like to be fed. Buy a lot of different brands of .22lr, and as many variations within a brand as you can find/afford to get. Then conduct serious accuracy testing. It's not at all unusual for a gun that shoots "patterns" with ammo A,B,C, & D, etc., to become a stellar performer simply by shooting ammo Y.
I've seen Ruger 10/22's go from so-so plinker guns to 75 yard one-shot one-kill varmint guns just by finding out what it wants to be fed. Just because your buddie's same make, same model, .22 likes SuperLeadFlinger ammo, doesn't mean your's will too. Two guns with consecutive S/N's can like completely different ammo.
