As was posted above the IIs and IIIs will shoot just about anything. I once bought some subsonic ammo and my Mark II is the only .22 out of 4 that would cycle with this ammo every time just like any other ammo.
The reassembly can be tricky but it isn't a big deal in the long run. Just beware the hammer strut. It is such an accurate gun and so much fun to shoot you will love it.
