Al,,I'm joking with you,I'm in one of my knucklehead moods! LOL!
I have only used the CPs so far,I am happy with the results so I haven't tried anything besides them! The time I really checked shots per fill,I had it filled to 2400psi & after 30 shots I had more than half of that left. my high was 1090fps & my low was 923fps,the 30th shot!
