    Evening everyone

    Just wondering if someone could explain a couple of scenarios regarding misalignment and crossover .

    1) If a scope was mounted 1mm out of true with the barrel (but still parallel) would the internal adjustment of the scope allow for correction without crossover . “Pretty much does the internal part of the scope move across but still inline with the main tube diameter”.

    2) If the mounts were not inline parallel with the barrel but instead it seated the scope at an slight angle (off axis) .... I take it this would show crossover . Let’s say if it was zeroed at 35 , the ranges closer would have crossover to the left and the further ranges would have crossover to the right ... or vice versa depending on which way the angle was.

    Hope this reads right as it’s hard to explain .

    Cheers

    It’s a hard one to explain

    On 1 ) If the scope was offset 1mm from the center line of the bore but still parallel , would a modern day rifle scope be able to correct this misalignment by using the windage turret without causing crossover .

    Scope would cope with it easy. if parallel - 1.0mm, pellet should hit same as offset - 1.0mm

    The answers to both of your questions are.... it depends.

    But, your real question should be - is 'crossover' caused by misaligned mounts. The answer to that question is NO, not to an extent where you'd be accurate enough to even notice.

    'crossover' is caused by cant and parallax error, not by misaligned mounts.
