Re: Why the love for MOA?

I dont understand how MOA can be more accurate than MIL, Could you please explain this for me?

    Not necessarily more accurate, but more precise in my opinion.

    a Moa covers 10.5" at 1000 yds.......a mil covers 36" at 1000 yds.
    a 1/4 minute click moves the bullet 2.6" at 1000, where a 1/10 mil click moves the bullet 3.6" at 1000 yds.

    For my eyes, it's easier to discern a 1/4 minute of spacing in a 1 MOA reticle than it is to discern a 1/10 mil spaceing in a mil dot scope. Even if they were equally easy, a 1/4 minute is a smaller measurement than 1/10 mil is.

    At a glance I can visually divide a square into 1/4ths. I can't visually divide a square into 1/10ths nearly as easy. The "squares" of a mil are much bigger.

    Hope that makes sense.?
    Don't get me wrong, they both work. They both do what they are designed to do. I just feel that the moa spacing is the more user friendly of the two.

    Really, Seriously?? I certainly didn't know that, if they are, then they're doing the right thing IMO.

    IPHY is so easy and quick.

    I also like to apply reticles for downrange zeroing and rangefinding. IMO it's a good idea to completely understand the math behind reticles in 2nd and 1st focal plane scopes, and how to apply them.

    We actually measured the size of a target at 1000 yds. to within .3" once using a mil reticle at a subtension other than std. milliradian (to obtain better accuracy). We had to mil a target of known dimension at a known range to calculate the subtension ("reverse milling") then remil the 1000 yd. target to calc. it's dimension. I have done this more than once successfully.

    As it turns out the most basic form of the mil-ranging formula actually defines rangefinding with any reticle (and even turret) as well as downrange zeroing with reticles and/or turrets.

    It's not often discussed but i agree that a backup system should be established in case the laser doesn't work.

    The more you know about your optic the better off u will be in the field.

    This optic system is a perfect example of that--



    It's the Nikon Buckmasters 6-18x mil-dot on a 17 Fireball XP-100. It has been responsible for a few 1st shot connections as far out as right around 500 yds. in some light winds on prairie dogs. I apply the optic at 18x for rangefinding and windage reference where the mil becomes 66% of the 3.6 IPHY std. mil. subtension at 12x (12/18=.667, .667x3.6=2.4 IPHY). Elevation is IPHY with turret.

    It is FUN to play with the math for long-range shooting...IMO!

    The practical solution to that is to carry a second laser rangefinder or at least a spare battery. Rangefinders are quite reliable. Who wants range readings which aren't better than 20% error? The problem with stadia reticles isn't reading the reticles or doing the math, it's guessing the size of natural objects. . You can get under 5% error if you have objects of known size in the field of view but how often do you have that?

    IPHY is????
    Does it matter what focal length
