azscot,
Try using a firm grip to see if your groups improve. Also check your pellet fit by pushing a pellet through the bore with a cleaning rod. Does the pellet pass down the bore tightly or loosely?
I had a Beeman Kodiak .25 for a long time. The best group I could manage was 5/8 to 3/4 inch c.t.c. at 23 yards and that was with a VERY firm grip with both hands and pulling the gun firmly into my shoulder......totally opposite from commonly accepted piston gun practices. If I held the gun gently groups opened up to 1.25 inches or more.
I also discovered my bore was quite large. I could push any H&N .25 pellet through the bore with a cleaning rod and it came out the muzzle with little or no sign of rifling. In fact, sometimes just the weight of the cleaning rod was enough to push a pellet through following a little tap to get it moving.
Airguns of Arizona recommended JSB Exact King pellets because they said they ran a little larger in diameter than the H&N's. They were correct and Kings proved to be the most accurate pellet by far in my gun.
I eventually sold that gun with full disclosure about its accuracy.
