Finally got some time to shoot today and my FDPCP groups like a shotgun and is WAY down on power. It used to chrony at 25 fpe with 14.3 pellets. Now it's all over the place anywhere from the mid 500s to mid 700s with the same pellets. Any ideas on what might be going on with it?

mind you, these are just things to check, if you haven't.
barrel loose (set screws), barrel o-rings, bolt probe o-ring (tried the tissue paper test?)

Make sure your adjusting nut is tight. They seem to come loose on some of the FD's.

Yes I did the tissue paper test and there was slight movement but it didn't come anywhere near blowing completely off. Have not torn it down yet to check anything else.
