Default Mil dot vs mrad?

Hello fellow Calgunners,

I'm ready to bite the bullet! (Okay, really hit the checkout button)

Deciding between the mil dot reticle with the .25moa or the Mrad reticle with the .10mrad?

And it's the 10x42 swfa SS (just in case your wondering)

You want the knobs and reticle to match so go with the mrad eticle and 1/10 mrad knobs.

In case you needed further clarification... a mil dot reticle goes by the mrad system... so if you have mrad turret adjustments, when you turn the turret to say, 1 mil... it's the equivalent of using a 1 mil holdover dot on the reticle.

If you have moa turret adjustments... you basically have a mildot reticle that is mrad... and then you are making adjustments in moa... so you have to do math.

Like the others said, get matching systems...

moa reticle, moa adjustments
mil reticle, mil adjustments

Mil > Moa

Mrads are easier to calculate on the fly.

Mil dots came from old artillery use. It's short for milliradian. It's a finner unit of measure than degrees. 6283.2 mils = 360 degrees, 1 mil at 1000 yards= 36 inches.

He said Mils are finer than degrees which is correct.

Not when it comes to scopes.

1 MOA at 100yds is 1.047 inches
1 MIL at 100yds is 3.6 inches

One click on a MOA scope is roughly 0.25" at 100 yards.
At the same 100 yards, one click on a MIL scope is 0.36"

Tell me how MIL is finer than MOA again?

Lightbulb A short & simple answer to your question, Exodus343...

Short & Simple Answer: The US Military used MOA because that's what was readily available at the time.

Back in the day, the US Military pressed accurate hunting rifles and/or match rifles into service as sniper rifles, and then topped them off with heavy-duty hunting scopes and/or match scopes. The US Military used MOA scopes because there weren't many other options out there which they could buy in large quantities.

Later though, sniper tactics evolved. The school of thought about sniping evolved too. So, optics manufacturers started producing MRAD riflescopes to meet the demand of US Military snipers. MAJ John Plaster and Clint Smith have both written good articles on the history and evolution of sniper systems. You should check them out.

FYI: Jeff Hoffman (Black Hills Ammunition president) came up with a practical windage formula using MOA if you're interested (http://www.millettsights.com/downloa...indFormula.pdf). Cheers! --1911ShooterPhil
