    hi wingers... what is the minimum parallax / focusing distance?

    thanks

    I'm not sure. 100 yards I think, possibly less. definitely not further.

    I am confused by your description.

    A First Focal Plane scope (FFP) should not have paralax adjustment?

    It is my understanding that a FFP scope's reticle gets larger in relation to the target as you increase the magnification?

    Why have Mil-Radian dots and MOA turrets as they are different systems?

    Confusedly yours, Simon
    Blindness to suffering is an inherent consequence of natural selection. Nature is neither kind nor cruel but fiercely indifferent.

    1 milrad is 3.6 moa, always has been as far as I know

    Its 2fp if ret is only correct at one mag. 1fp and 2fp scopes both need px adjustment for shooting at range.

    They are front focal

    A first focal plane scope's ret stays relative to the target at all mags, hence you can range from the graduations at all mags. A 2fp scopes ret is generally calibrated at one point, although you can work out the relationship at other mags with some simple math, but you probably wont position the zoom correctly, even if the scale is accurate.

I am not an expert in optical instruments so cannot help you for sure on whether or not the focal plane in which the reticle is held makes a difference as to the presence or otherwise of parallax. However, parallax is caused by a difference between the focal plane between which the target image and reticule are being viewed so whichever FP the reticule is in there can be a difference and so parallax adjustment useful in either case when a great variance is experienced between target ranges. I think I can accept Offroad Gary's comment that either way its necessary / useful.

    It is my understanding that a FFP scope's reticle gets larger in relation to the target as you increase the magnification? No. in an 1FP scope the cross hair will cover the same amount of target at any distance (it may appear 'larger' but is in fact identical. In 2FP the cross hair covers a progressively smaller amount of the target as you increase the magnification.

    Why have Mil-Radian dots and MOA turrets as they are different systems? Not really. Same system, different units of measurement. I have no idea. Ask Mr Leupold.

    Confusedly yours, Simon
    Thanks for your interest.
