Ok total honesty here. I just got into PB and was able to by a G4 new on Kijiji. Gased up and went to field and all works great not a single issue other than when i try and crono and set to 280 i can only get it to go to 265fps. NO more. Adjusting the screw seems to make little difference from full in to full out(i almost dropped it) Any thoughts. I will be looking at it more but thought i would see what you guys around here have to say. On another note. This was my second time playing PB ever. Don't know how i ever missed out on this game before. What a blast.Put over a case thru on first day and not a single blip. Worked flawless other than the speed thing.
