    .17hmr hold over / under question

    Hi Guys,

    Sorry if I'm being thick here but can you please clarify this for me, my hmr is zeroed at 100 yards. At 70 yards the drop is +0.3143 so that would need very small hold under. At 10 yards it says -1.04, so at that close range you would need to roughly 1 inch hold over ? I always though for closer ranges it was hold under, probably me just getting confused My the way I not shooting anything at 10 yards but want it clear in my mind.

    Thanks

    Steve

    if you zero at 35 yards you have a very good trajectory out to 125 yards give or take a few feet,

    this is will mean that all you do is point and shoot,

    done me this for many years and never changed it on all 5 hmr rifles I have had,

    regards

    Steve,
    Best way to think of it is barrel and Scope
    if your scope is 1.5" above the barrel the bullet will leave the muzzle
    but appear 1.5" low if you are sighting through the scope.
    so at 10 yards it might be an inch low
    at 25 yards more or less zero right out to 120 yards.
    as in Robbies diagram

    You might need to take a 3 yard shot on occasions so
    either use a mil dot or ballistic reticule or allow for the height of the scope
    and aim 1.5" high! "

    Steve I'd put targets out from 10 yards to 100 yards every 10 yards aim at the same point and see what happens theory is fine and I'm not saying anyone's wrong but if you see what it's doing you'll know when a rabbit pops its head up where to aim
