sniper bullets way high even with range finder

was playing matches after season two update and found even when a target is sitting still and my sight was on target with the range finder equipped bullet went way high almost to the point where I had to put the top of scope on my target to be even remotely close sliding and changing weapons seem to get the gun back to firing properly and also still dropping squad mates left and right having to back out go in multiple times before we even get into a match
