George,
Had a varmit, shot the best of all my CZ's(got 4 now, have sold several), but I think it was only due to the extra weight out front and the shape of the forend and how it settled into my front rest. It would shoot pretty close to 0.300" at 50 yards with it's favorite ammo, they all pretty much shoot at or just under 0.5" at 50 yards with preferred ammo.
Take Sheffeild shooter's advice and try varying the pressure of the forend screw. If that doesn't fly try removing the screw and making sure the lug is not contacting wood.
Had/have two trainers that I quit using the barrel lug screw and drilled and tapped the action for a second action screw (easy to do, but a little work and there is not much meat for the 2nd action screw but I've had no problem)shot pretty much the same, no major improvement.
I had three scouts, they all shot fine. Put a second action screw on one, and again didn't notice any major improvement in groups. Will note that I've glass bedded all of my CZ's.
Haven't tried the Basix trigger (yet) or the Timney for that matter. Tried two of the automation solutions adjustable sears... like them. Also bought a trainer that the previous owner had set the trigger up with one of the trigger shim kits (ask who is selling them now over at rimfirecentral), they run around $18 and this trigger is as good as the triggers with the AS sear.
Oh yeah... What ammo are you using? I have had the most consistent luck(?) with Wolf Match Target. Even that can depend on the lot of ammo... Wolf match Extra is supposed to be more consistent than WMT (it's more expensive) but the lot that I have does not shoot as well, SK Jag Und is the same round as WMT with a different name on the box yet the lot I have does not shoot as well as WMT in several of my rifles. The best groups I shot with my CZ Varmit were with of all things PMC Sidewinder, so it pays to try different ammo.
