Hi all, have an m4 I'm having issues with the hop. I have tried everything from standard prommy purple, maple leaf and s hop, all do the same.. I have a consistent 330/331fps on 0.2g but every shot is different, the bbs fly perfectly straight but the vertical action of the bbs changes every shot, some go 6ft higher then others, what could be causing these random shots? Could nozzle length affect this? Can't think what else would cause this. I've also tried different hops, standard cyma, zci and a prowin
Or could it be a tappet plate problem not resetting the bb in correct place on each shot?
