S510 U.S down in power!

[Kop77]

Hi all,

I have about 500 pellets put through my new S510 Ultimate Sporter Xtra FAC and I noticed today that the power seemed to be down as the pellets were not penetrating as they used to!

I popped the chrony on and sure enough instead of the normal 30 odd ft/lbs all in getting is 9 ft/lbs on full power and about 4 on minimum.

Anything I can do or check myself before I go back to my local gun shop,

Thanks..

sounds like the power adjuster has moved and is closing the transfer port, take it out of the stock, there is a locking screw underneath the adjuster, set the power and lock the screw, don't over tighten or the seals will leak. Rog
