moa vs mils, the forbidden thread

People still dial anything after zeroing? The only thing I dial is the power ring to change the range/drop setting on a SFP scope.
Yeah, you can hold both elevation and wind. I've done it playing around with H59 reticles/tree reticles. I do find I get lost less if I dial the elevation to a mathematical consistent variable like gravity, but hold wind since the SOB can change by the second.
 
🤷‍♂️ here I was thinking there were 6400mils to a circle… at least in the Army/Artillery world. Different kinds mils or something?
Back in post #114
True Milliradian is rounded to 6,283.185307179586…../circle

I might have these labels incorrect, but I believe it to be.

NATO 6,400/circle
Warsaw pact (USSR) 6,000/circle
Swedish 6,300/circle

I would guess that all modern riflescopes in the US market are based on true Milliradians.

Lowlight elsewhere mentioned that artillery used 6400. USMC and I think the rest of scope companies use 6283. He also said difference between 6400 and 6283 is less than 2%. Since it is based on pi it has to be rounded somewhere.

Koshkin would know but I don't want to at him in this thread.

Yes, different mRad. This is who it is important to know the actual measurements in your scope. Is it MOA or IPHY? The difference id small but can be important. MRad or rounded? The difference is small but important…

It doesn't matter what unit of measure is used. You can build a house with a tape measure graduated in inches, centimeters or anything. Its simply a comparison of a graduated scale. The wall I need a baseboard cut for is 96-1/2" long, or 245.1 centimeters. Your tape measure could be graduated in anything, say golf balls or cheez-its for that matter. As long as you use the same tape measure it all comes out right. Use the UOM you are familiar with. I am an amatuer machinist and I have always worked in thousands. My dials are graduated in thousands and that's what I'm comfortable with. I have a reference for what .010" is and its natural to me. Trying to do things in metric is just not what I'm used to so when I machine parts I convert to imperial. For shooting I always use moa but its because its what I'm familiar with.

If you are converting anything to linear when using a scope you are doing it wrong.

Also moa and mil have nothing to do with linear when using the scope.
 
Agreed, measure in prefered UOM and correct in same. The scope isn't graduated linear measurement but rather angular. Converting to linear is an extra and unnecessary step.

Exactly and knowing that there is no reason you couldn’t use a mil scope if you can use an moa scope. Just a different number being dialed or held.

Most do not understand this at all. You are ahead of most.

I'm an aerospace grinder machinist and I mostly use tenths (ten thousanths). Just an extra zero.
 
Here is what I stink. Except math for ranging a target in reticle, just use the reticle for corrections. For example, during zero, maybe the initial group is 1 MOA high and almost 2 MOA right. Instead of counting inches, just do the clicks.

I don't know how many are ranging in reticle. I know that I sometimes do that in the very thick woods where the rangefinder may reflect off of something only 30 yards away when my target zone is farther than. So, knowing the width of a tree trunk in the desired zone, I can do the math and arrive at an approximate range to target.

It would not matter if I used mils and determined range in yards or meters. Math is math. I ain't askeered of math.
