Does it matter how far apart your scope mounts are?

    You'd have thought so, the further apart the more stable, less flex.....but there's bound to be something out there to say the closer together allows for firing cycle movement or something or other.

    I don’t know but I’ve always liked to keep mine as far apart as possible.

    All depends on how big your hands are. Too close and you wont be able to use scope as a handy carrying handle

    It affects the max MOA available from adjustable mounts.

    It affects the torque/leverage applied to the structural weak points of the scope in the event of something nasty happening... bump. :( Seem to remember there being a school of thought that as wide apart as possible would be best in case of such incidents. Mind you things have come a long way from the ASI 4x40.

    Technically it must stiffen the action but if that is relevant you'd need to look at the geometry of the gun combined with the mount separation. Can't really seeing that being relevant...

    Most importantly they should be positioned so they look cool and don't foul your wheel, pointers etc.

    So er... No... is that the right answer?

    Take note though some scope manufacturers state that they should not be to close to either end of the scope tube, I presume it something to do with to much undue stress on the adjustment mechanism or lens assembly’s?

    I suggest using only one anyway - to save weight :)

    It changes the angle imparted by a shim of any particular thickness.

    Angle is equal to inverse tangent of shim thickness divided by mount separation.

    I recon if my scope rings were 40 yards apart I’d get more long distance kills - tricky close up mind .....

    As long as your ring distance isn't greater than your scopes tube length I don't think it really matters.

    The further that they are apart the more the scope will be affected by differential expansion of the scope and action when heated and cooled in/ out of the sun, therefore affecting the bending moment on the scope and then the POI as viewed through the scope..... just a thought like!!

    I'm surprised that no one has used the entire rail filled with identical mounts to provide the ultimate scope mount.
    Might have to get some wet and dry on a dowel to flat some variation... ;)
