My .223 Continental Varmint is fairly outstanding; .7 MOA with lighter bullets. As the earlier poster mentioned, twist is a bit fast for anything upwards of 60 gr, but if you're actually going to varmint hunt with it I can't figure that would bother you, and the 1-9" twist of the CZ (if it is so) would rip apart light-jacketed 'super explosive' bullets (not that those are really necessary anymore, with the availability of components like the Hornady 40gr VarmintMaster). Rings, by the way, are no longer a problem -- Weaver top mount bases are readily available for about $3 each. CZs are fabulous actions, and I'm seriously toying with the idea of a scoutish conversion based on the 7.62 527 carbine; but I think you'd find the Continental Varmint to be a better out-of-the-box choice.
