Hi i have a dm8 and have had quite a bit of drop off compared to other guns at training. Also the shots do vary in where they hit when i am shooting dead at the same spot. It either goes up a bit further or left or right of the spot i hit before:S.(this is also not from a rediculous distance either) i have the stock barrel and used celtic banshee and a dye throttle tank. if anyone has any ideas could you let me know ? cheers guys (also forgot to add that i made sure the tank was full and the battery was new )
