Hi all, This S200 (.22) is fitted with a Huma external regulator and has me puzzled, the pellet probe and cylinder seals have been replaced as they are a 5 minute job and no trouble.
What happened is this, running at 11.3 ft-lbs and suddenly noticed ,literally one shot to the next, that the sound had altered and sounded 'soft.' checked and it had dropped to 9.2 ft-lbs and varying. Winding the hammer spring up makes no difference, tried new spring, same.
Any suggestions would be very welcome.
Many thanks.
Cheers.
Geoff.
