FX Panthera Hunter Compact .22 power settings.

There is not a universal answer that will work with every gun. You are going to get several different settings and ranges of velocity or pellet. Best you can do is learn to tune your gun from a variety of pellets that you test to see which works better for you. I would get a tin of AEA, JTS, JSB, FX, AA and start there. Shoot for a velocity between 840-880 fps and see which pellets shoot better in your barrel.
