Have you tried reducing the valve orifice? They have their Ring-loc kit, and other aftermarket suppliers have theirs, like Talontunes. The idea is with a smaller orifice, one can shoot at a little lower velocity more efficiently, and for a .22 slug in that gun that might be subsonic but still fast, use less air and have a broader shot curve. Not regulated but more usable shots per fill.

I tried this today with my Condor, coincidentally, and with Airforce's 0.123 orifice had a .22 20gr slug flying at 905fps with the power wheel at 6, and 973 with the wheel at 12. I estimate that orifice will give me close to 100 useable shots per fill, although I may have to dial the wheel a little through the shot curve.
