mrad vs m.o.a

[runstewart]

hi what is mrad and how would you work it to m.o.a is mrad better or is m.o.a and how do you work out the difference thanks

MOA is a concept (one inch per 100 yards or thereabouts) which is easily assimilated by the average guy & can be applied to adjusting precision sights of various sorts to the fall of a shot on a target. Miliradians relates more to angular relationships & is more useful in a military dropshort environment. See http://en.wikipedia.org/wiki/Angular_mil

They are both angular units of measure.
.1mrad is 1cm at 100 metres and thus 10cm at 1000m.
F class targets are sized to correlate to moa measurements to be "easier" for call of shot and sighting adjustments, for moa thinkers.

They have both been around for ages and are both used in the military.
I use a mrad scope and I would adjust my shot after seeing where my sighters land via looking at the mil reticle in my scope. I do this for our weekly club comps with electronic targets too.

However for f class, moa "might" be better, but I'm not changing.

Also google is your friend, and there is tons of info on the subject which is not hard to find.

MOA for scopes is definitely better, mainly because virtually all F-Class shooters use it, and understand it. You'll probably be competing in a team shoot before too long, and your coach would throw his hands in the air if you told him your scope was in mrads. Get a 1/8 MOA per click scope, and you won't regret it.

0.1 mrad = 0.36 moa (approx) > 0.25 moa which is already too much minimum adjustment for the fclass job.
keep safe,

...and your coach would throw his hands in the air...

Yes Alan, you are quite right .

Although when I get to know you a little, a gentle crack over the back of the head will surfice

As a rule of thumb the main scoring rings are roughly .5, 1.0, and 2.0 MOA in diameter. Now there is a principle that I like to work with, and it is K.I.S.S.

When you are in the middle of a tricky wind patch, do you really want to be calculating .36 times this or that or simply multiples of MOA. I know which one I prefer, and you'll find most TR and F-Class boys and girls will agree.

As Bruce indicated, 0.1 mrad is already bigger than we would like. 1/8 MOA gives us the ability to centre a group vertically. Using 1/4 can see your group sitting above or below centre line by quite a bit, causing you to miss out on a few X's, or more importantly being blown out of the Centre!

Stewart, it is ultimately up to you what you end up getting, and if you just love maths, then you may wish to run mils just for the challenge

I love telling people: "I'm allowing about 1.2-1.4 mils for the wind"

Say......whaaaaat......????

Hahahaha, I do the same Casey, some guys look at me weird.

One thing that is good about mils is that the Kongsberg electronic targets show the x and y axis distances in cm. Its the bullet hole distance from centre. makes it a tad easier to see how much your off.

When im being coached, I tell the coach to just give me moa calls and I adjust myself. 0.3Mil is very close to 1MOA.

I will admit that if/when I build a dedicated F-Class rig, it will probably have 1/8MOA clicks for fine adjustment.....unless I can get 0.05Mil adjustments........
