My favorite is pobably my most recent because it is new, the Ataman. I de-tuned it to 25 fpe and the report lessened considerably. I have enough 30 fpe .22, so I wanted this to be downgraded. The action is soooooo smooth and the trigger is really a 1 stage operation, but I have it set very nice.
The top of the list, last on to go would be the Colibri. If only it had a walnut stock(winter project) then I would leverage the world to keep it. The side bolt is so short and diliberate and the CZ barrel is very nice. Quite gun at 30fpe with 70 shots per fill. Shoulders in tight and comfortable.
If they came out with a .25 cal., I would sell the rest and settle on Colibri only as my stable.
