Panthera The Ever Climbing Velocity PANTHERA MKII

[Billm]

I mentioned my FX PANTHERA MKII has a climbing velocity string. It starts out low and continues climb. Doesn’t seem to be leaking. Has the Huma Reg installed. I just changed the valve and valve seat. I’ve tried 120-150 bar. Here is my last string.

If I were to guess, REG Creep or valve. these rifles reak havoc when de-gassing & tuning. Watch your reg before & after each shot for any in concistancy, to eliminate the reg , put back your amp reg in to test it again, Process of elimination

I know there is some creep. But, it seems more than that. I will put the amp back in and see what that does. I’m hoping I’ll get a glimpse of the Limited Edition Panthera with bull barrel while I’m at the Pyramyd Air Cup.
