    I've been looking at the new little redfield scopes and they have a ret that is called tac-moa ?? It looks like the hawke half mildot
    but they say it has 2 moa spacings?
    I am not familiar with what moa equates too.....
    It's primarily designed for .22 rim fire and looks a perfect little scope for my little gun.
    but before I try and find one to look through I wanted to check it's suitable.
    Ideally I'd like it to be half mildot or similar.
    Cheers

    Ok so I've done a bit of reading and now I'm even more confused.
    Basically all I want to know is Wether the aim points are closer together than the hawke half mill ret? The same or further apart? At the same magnification of course.
    :confused:

    Found this does it help ?

    TAC MOA is Redfield s tactical reticle. This reticle has hash marks with 2 MOA increments. MOA marks makes it more comfortable in use comparing to milradian based reticles. 1 MOA is 1″ at 100 yards, 2″ at 200 yards and so on. On the other hand 1 mil is 3.6″ at 100 yards, 7.2″ at 200 yards and so on. As you can see it is much faster to do calculations using MOA based reticles.

    Redfield TAC MOA reticle has 40 MOA hash marks spacing (20 MOA on both sides of the center). Then there is 20 MOA of solid line. Tips of the heavy posts is the 40 MOA.

    Actually I think it does...
    2moa 2" at 100 yards.
    .5 mildots 1.9" at 100 yards. At approx 10x mag.
    so the half mildot markings are fractionally closer together then. Although the moa scale appears to suit my maths better.
    But then the little scope only has 7x mag how does this affect the scale?
    I had read on the leupold site they where calibrated at max magnification.?
    Anyone using one of these scopes or had a play with them?

    Cheers eyewitness!

    I know you've already come up with the answer, but just another way to arrive at the same answer would be...

    1 Mildot = 3.44 MoA
    ½ Mildot = 1.72 MoA

    So if the scope has got 2 MoA spacings, they're a little bit sider apart than ½ mildot spacings as you've already figured out.

    Cheers brian. Is it fairly normal that it would be calibrated for its max magnification . This case 7x mag.

    Yeah, that's pretty normal for low magnification scopes. If I had to put a bet on it, my money would be on 7x mag.

    7x is a little on the low side and scope manufacturers tend to round up when it comes of mag.. so it might say 7x on paper but end up being 6.4x in reality - just something to be careful of. If you can have a look through it to see what a 15mm kill looks like at 25 yards.
