Heres a video of Tom Knapp..using a CZ/Bruno .22 mag auto. He starts out with the Benelli shotguns , but switches to the .22 mag at about the 4 minute mark:

Buying an accurate .22 mag is a "crap shoot"... I had a .22 mag which shot very well (an Anschutz) but gave it to my grandson upon his coming home from Iraq duty which included sniper work.
Since then I tried a couple bolt .22 mags to replace the Anschutz, but 1.5" groups at 50 yards are not good enough. I about gave up..trading my last, a very pretty Marlin with cinnamon laminate stock, for a Savage 93 in .17 HMR...which duly impressed me.
Then one day i was visiting my local dealer and spied on his rack, a new Savage 93F ..plain-Jane with fiber stock.. @ $179. I just HAD to give that a try!
Well, that little Savage is the first one I have seen that will shoot right along with the Anschutz I parted with about 6 years ago.. If you were looking toward a bolt..I'd send you that way, but auto has to be CZ..
I have just one CZ..a 452 Special which I had that same grandson cut & crown (about 6.5") for me (he's also a gunsmith).. it shoots like a dream..
