[sundriftrotts]

I checked my txt through a chrony yesterday ft pounds has dropped to 8.5 normally it's 11.7 anyone any idea why

broken spring ??? or breach seal shagged

have you put new batteries in the chrono ?

I'd go with piston seal, spring, or breech seal. Breech seal is easiest to test by laying a tissue over the loading port and firing. If tissue blows breech seal is defective.

It is also possible latching cocking arm is not pushing far enough forward to seal.
