For paper Wolf Match/SK Plus is a good starting point to see what the RIFLE likes. If you are more discerning, Wolf ME/SK Match. This is NOT to say your rifle will not perform as well or better with something else. It's simply a good solid proven go to ammo recommendation.
Hunting, buy what you can find for now and see what it shoots the best with...buy some more but always be open to the fact that the same ammo brand can shoot very differently from lot to lot. Having said that, always keep an open mind when buying rimfire ammo.
Beautiful CZ, now the fun begins. Countless hours of it. Looks like a Bushnell Elite Tac. Did you go with the G2 reticle?
