I've had good results with:
CCI Standard Velocity
CCI Mini Mag
CCI Stinger
Winchester Super-X
Federal American Eagle
Federal Gameshock (bulk pack stuff)
Aguila Super Extra Standard Velocity (smells funny but shoots good)
Aguila SSS (you can feel the recoil on these. The bolt really slams back.)

What didn't run good:
Subsonic ammo. Tried Remington and Aguila. It doesn't have the energy to cycle the bolt.
CCI Shotshells. (No recoil to work the bolt, but they fed great as a straight pull bolt action.)
Remington Thunderbolt (lots of misfires, lightly loaded rounds, and feeding problems.)
Remington Target 22 and Golden Bullet didn't run that well either.
I did run a box of Remington Yellowjacket with no problems though.
