The real problem with 22lr/accuracy/low cost firearms is the fp/ignition. CZ's are excellent firearms and with some bolt & trigger work will flat out shoot. Back in 1996 I bought a NIB CZ 452LUX, back then they were imported by MRI in minneapolis MN and had triangle shaped boxes.

Now their imported to KC and have square boxes. Always liked that pencil bbl'd CZ lux and in 2008 while I was building that 10-22 I worked on the bolt on the cz lux. Did a bunch of polishing and moly treating the parts along with a heavy duty striker spring and re-shaping the firing pin tip. I used the russian Vostok ammo as a test bed. A lot of people bought the vostok ammo over on rimfire centeral and had issues getting it to go bang when they hit the loud button. I saw that and said good & bought a case of it to test firearms with. What the fp hit looked like on the vostok ammo after the bolt was re-worked.

That cz lux had no problem doing 1/4" 5-shot groups @ 25yds. The problem was it could only do 1/4" 5-shot groups @ 25yds. After the bolt re-work the groups were cut down by +/- 40%. Typical 5-shot groups after the re-work. Note the 31* jan-31-08 ohio winter temp the day of testing.

Same rifle doing 50yd 5-shot groups. The result is listed in mm's because I was doing a 50yd 13mm game over on rimfire centeral.

I owned/shot a lot of rimfires over the decades & tend to lean toward the sporter rifles. I do own/use bull bbl'd target rifles, but I don't shoot them that much anymore and have been thinning the herd. Sold my last winchester 52d this year along with a remington 40x. I can easily say shooting 22lr's @ 50yds is childs play compared to 100yds.
