Chrony results for a P17

well not know the weight of the pellet you are use I would say 112m or 367+fps is ok and the other not even close at 253- fps

so your new chronograph is not reading right or your pistol is not shooting right and you would need another gun to test or another chronograph, can we say pickle

I'm shooting a 7.2 gr Beeman HP pellet. 

I checked the chrony on two of my other guns, but I will do some more testing to see if it's a chrony problem.



thanks,

so the chrono is fine then it is the pistol and the history of p17 problem aren't new, so more testing or

you might put a little lube in the cylinder hole on the p17, a thread on the subject but just Google it you should find more and if does nothing it will be a o-ring problem on the piston
