Hello everyone. Last weekend i tried to chrono my automag rt. I was shooting really high and then tuned it down to around 250. within a few shots i range from 190 to about 260 with out adjusting the marker. Mostly it shot +/- 25 fps. I tried using the gold spring instead of the red one, i had the same issue. I tried using a standard tank instead of a 950 psi tank with the same result. I made sure that the marker had oil in it. I am not sure what else to test. I am using a level 10
