I am getting fluctuations from 740 ish fps to 850 ish fps and have removed and cleaned the regulator with no change . Any input would be appreciated.
Thnx ahead.
Thnx ahead.
Accuracy is somewhat affectedCan you post a pic of your rig?
Is the accuracy affected?
Is air escaping anywhere?
Are you using a moderator?
Some things that come to mind:
Check barrel is secured tightly(doesn't move) and aligned correctly with respect to rotation and depth to make sure the transfer port hole is aligned correctly.
Check for pellet clipping.
And you did check the inside of tube where the hammer/striker rides for a marks or galling or. If you slide the hammer in is the hammer able to rock about much at all? I do not know that rifle at all but have seen different brands (esp used, well only used) where the hammer could tilt & drag and have seen an out of round tube. Make sure to check the entire lenght it travels.Again Thanks for your input. The Probe is set perfectly. Today i brought the reg pressure to 130-140 bar and shot some strings.
with the same extreme spreads from 12-89 fps in 5 strings. What I did notice was a sound difference from the hammer hit from time to time. While i did inspect the spring, hammer and weight I cannot point to any obvious weak or bad component . Any thoughts on this matter will be given consideration.
