There is someone with the Sumatra .22 500cc.
HOW MANY SHOTS PER FILL
THANKS

This is not the answer you're looking for but I got one but never shoot it at full power, just too loud for the neighbors. I've read somewhere around 20ish shots before you notice the POI drop. Best to settle on 900ish FPS and use the power dial to maintain the velocity. I actually use the gun at much lower power levels, unfortunately its not as accurate with lighter pellets and lower velocities. At the lower power levels I get more than 50 shots using 14-16 grain pellets at 800-900 fps.
