For the balls all over the place, check your FPS. Could be shooting hot. Of course, if you have paint in your barrel, that's going to make them go everywhere also.
Is the paint just in the barrel? Or is it on the bolt? If it's just in the barrel and hardly any on the bolt, those are barrel breaks and not chops. If its all over the bolt then that's a chop.
Need some information though - what loader do you use (is it that Evolution you have in your sig?), and what setting is it on? How fast are you shooting? Are your eyes on? What paint are you using and was it new and fresh?
