I had one that shot great like .5 for 5 shots with factory ammo, then one day for some reason it just would not shoot as good anymore, like 1 moa for 5 shots, I had the action skim bedded to the block, didn't change anything, its a light rifle for as heavy a barrel as it has, the stock came with a very very short LOP, from what I hear CZ back in czech messed up when they ordered these from HS and speced too short a LOP, didn't matter they sold the guns anyway with short stocks. for me a guy that likes a 14" LOP this is an issue. make darn sure to see which stock the gun has, the one I had had a like a 12.25 LOP which is rediculous.
personally i don't care for clip fed guns, I still can't get used to the safety, I still have a 527 carbine 223, but sold the kevlar varmint, I think tikkas require no tweaking out of the box, the trigger is simpler to adjust, I do think a CZ will shoot with a tikka but it may need a tweak or 2 to do so.
