So I've got my bar-10 pretty powerful now ~590 or so. Edgi 6.00 ported KA bucking all the works, but I still cannot his a torso size target at 40 yds. with any kind of consistency. I'm having lots of problem with curvature. For a while I was curving to the right, I shimmed the hop up arm fixed it for a while and now I'm getting random curvature all over the place. I'm using GB .30's and I haven't had any sort of problems with them before, could this be the issue? I'm getting curves every direction even like a curveball in baseball (if that makes sense) and curves left right up and down. Any help is appreciated.
