I was recently given a new 10point crossbow, package deal with a fixed power scope. I've shot it on two different occasions and both times the following has happened. The first handful of shots group nicely in the bullseye, then the group shifts an inch or so the right.
Sunday I was shooting at 20 yards. First few shots with a nice group in the bull then the group shifted to the right by a bit less than an inch. Collected the bolts and the next group also hitting to the right, so I cranked the scope 4 clicks (each click half inch at 100 yards) and I was back in the bull. Shot a few more and the point of impact again shifted to the right, this time by more than an inch. So this time, I cranked the scope 10 clicks and the next group was back in the bull.
I'm worried that something is wrong with the scope. If I were inconsistent with my shooting, it seems like some of my arrows should end up to the left of the bull. I adjusted the scope 14 clicks. that should be 7 inches at 100 yards or nearly 1.5 inches at 20 yards, yet none of my bolts impacted to the left.
How do I confirm whether my scope is bad or its operator error?
