Took my new PT 22 out for the first time today. Found out that CCI plain lead nose bullets do NOT work. The shell in the chamber would fire but there was not enough power to eject it and feed in another shell. I switched to CCI hollow points and it works beautifully. 100 rounds with no problems. Amazing little pistol. I had good scores in a 4" bull at 30 feet. Better then I expected.
