CCI Standard serves me well. I shoot all my .22s at a 100 yards, and with a rifle like an ES340b I get 5-shot groups just over 1". Wolf Match is pretty good if you desire more accuracy.
I see no point in wasting $ on the more expensive match ammo. I have tried it all on a .22 scoped Schützen rifle at 100 yards, and settled on the Wolf ammo. 5-shot groups are always sub-MOA.
