Cedric 132 Posted September 2, 2014 Report Share Posted September 2, 2014 I've just spent an hour drawing diagrams to try and get my head round the phenomenon of crossover with scopes. As far as I can see, a scope fitted parallel to the bore but not directly over it will result in crossover. i.e. sighted dead on at 50 yards will shoot to one side at 100 yards and to the opposite side at 25 yards. I have noticed this on one of my rifles. Apparently a scope fitted at an angle to the bore but directly above it will shoot straight after the reticule is adjusted. If we take it that the factory cut the grooves correctly that leaves us with the mounts, Should they fit to one side at all, crossover will occur. Is there any sensible way to check this fit? And, I suppose, good quality mounts would less liable to error. Quote Link to post
