Have you checked to see that your barrel has no play up and down with the lock detent on breech. Reason I ask this is because I would get the same kind of groups from one of my S1K's.. It did not lock up tight after cocking. It seemed that the detent pin on the action side was miss aligned and after it got about 3000 shots it started to loose accuracy. Gamo changed the design by using a pin on the action end that went from side to side. All my other Gamo S1K's have the later pins instead of the detent lug sticking out of the action. Check it by cocking it and puting the rifle on a solid surface and take hold of the barrel while holding the stock and action tight. See if there is any movement up and down.. It drove me nuts for a week and thought my scope was broken..
I ended up throwing the action in the trash.
