Ok, I installed a huma reg and only getting 27 shots with a .177 cal. The edgun leshiy is in .177 with a 250mm barrel. I decreased the power of the gun and yet the shot count has not gone up that much. I could try to turn this into a 12FPE gun shooting 8.4 jsbs but the trade off just does not seem worth it for lack of shot count. So I am shooting .177 10.3 grains jsb pellets at 800 to 830. Only getting about 27 shots at about 14 to 15 fpe. This seems very low as people have noted the ability to get 20 shots with a huma reg installed in .25 cal with 800 fps which equates to over 30 FPE which is about double the power yet 3/4 shots. Some side notes of the tune. The huma regulator is set to about 95 bar. The gun starts out at 250 bar and runs down to 95 bar. Per other users they indicated filling the gun up to max of 300 bar but that only gets users an extra 2 shots. The gun blows too much air at 300 bar thus users are going to 250 bar. After the gun hits 95 bar the POI impact changes by a few mil dot at 50 yards basically the gun appears to be running out of air. There was another poster on a lehshiy forum that indicated he was getting 33 shots with a .22 cal jsb 13.3 grain at 775 fps. This was with the standard regulator not the improved one. Any help on how to get the gun to shoot efficient ? jay Anybody offer any tips ?
