MOA or MRAD Adjust?

I went through that dilema myself and ended up with MLRD-16 and MOA knobs. The friggin' long range simulator trained me so well that it was a step back for me, plus every one talks MOA when adjusting for trajectory here in NA.

like i said earlier to the OP .. pick what you're comfortable using.

here in NZ we are brought up on the decimal system of meaurement

so when a shooter says that they function on milrads its almost a relief, because cm's are an easier unit for us to guage than inches.

we generally have to adapt to inches because 99% of scopes are in MOA

Object size(Meters) x 1000 divided by Object size in Mills = range in Meters
Object size (Inches) x 25.4 divided by Object size in Mills = range in Metres

Object size (Yards) x 1000 divided by Object size in Mills = range in Yards
Object size (inches) x 27.77 divided by Object size in Mills = range in Yards.

Example - 72" target = 4 mills
72 x 25.4 - 1828.8
1828.8 / 4 = 457.2 Meters

Mrjohn, this isn't aimed at you, just an expansion on what you posted.

1 Mil = 1m @ 1000m so a target known to be 1m in height/width that measures 1 Mil is 1000m away.

I have a range estimation chart here somewhere that is used to do range estimation when engaging targets with a tank, I'll look around for it. You may not be shooting at T 72's with your rifle, but it will show you the principle behind the Mil system.

There are a few guys on the site with experience on the C3 and newer guns who may chime in with a different chart for smaller targets.

Some of the rifle data books have these charts included.
They give the size of common objects such as stop sign, door way , 45 gallon drum.
The military charts are designed for man size tragets as well as vehicles.
If memory severs me a T-72 is around 2.5 mills @1000M,
And as said - please don't shoot a T-72 with your rifle - it makes them angry.

the important thing in my books is to have the adjustments in the same measurement as the reticle. If you have Mil adjustments...it is nice to have the reticle in mils. Same with MOA with an MOA reticle. It is insane to have MOA adjustments and mil reticle. The potential for math errors gets higher and when your tired/stressed you will make a mistake....

Keep them the same...
