I was shooting my xbow yesterday. I shot about 20 bolts hitting inside a 2" circle every time. Shot 21 went 8" high on my block target. Next shot went over the block completely. I ended lowering my crosshairs 40 clicks, completely bottomed scope out. I am right at the top of the 2" circle now. I have removed every bolt, put on new locktite, replaced scope rings, and problem is still there. Anyone ever had this happen to them? I am going to replace the scope. It is a scope for a xbow so it is the right kind of scope. Just really weird experience.
