My CZ shoots pretty good, under MOA most of the time, anyway. I haven't worked with any powder except 1680, either, so that's withOUT much experimenting or tinkering. I wouldn't overlook the CZ without at least trying one out, if you can find a buddy with one to loan you.
I don't hotrod mine, I have "other rifles" for going fast............
And the set trigger is sweeeeeetttttt...................
