Those angled shots are more difficult, the size of the target is narrowed - thus smaller. Your difficultly and the results you often get are no diff. than every one elses. Its requires finer shooting. I think what you are experiencing is pretty typical i.e. 45 deg left leads to the majority of errant shots to the right as opposed to the left. The fix? just keep practicing-- with time you.ll learn to make the correct ajustment. Its really is the same thing as trying to stick a sheet of paper that is flat out facing you, as opposed to trying to hit that paper angled at 45 deg. away from you, or towards you for that matter-- its just a smaller target, and errors are magnified. Don"t you just love the variety of challenges presented you? Keeps it ever interesting!
