You might want to have a look at the first sticky....it addresses your topic but you will see a wide variety of opinions. I expect whatever someone purchases that works in their pistol gets added to the list. Just about anything CCI is good. Bulk ammo, read less expensive, is led by Remington Golden Bullets. Then of course it depends on what you are doing with your pistol. If competition then RWS or Eley, etc. or a better target pistol....with apologies to Mr Crete who seems to be able to knock off $3K standards with his old P22.
With my suppressor on Rem Subsonics and CCI Quiets works very well for cycling while staying quiet. But for overall reliability of cycling you must have a round that develops enough blow back energy to cycle the slide.. And, you must hold these pistols firmly when firing. On the other hand, the most powerful .22 ammo I know of, CCI Velocitors do not always cycle reliably in the suppressed pistol while most every other ammo does. Why not...blowing the slide back too fast....???? I don't know. 1917
