MOA MilDot - I just can't get it

[disabledamerican53]

I think this is extreme for the 22lr.
I have a Barska 8x32-50 1/8 click value scope on a 22lr rifle.

1. If I zero at 50 yards, and the drop at 100 is 11.6 inches HOW many clicks do I change to get to 100 yards?

2. if I zero in 100 yards how many clicks to real 200 yards 48.78 inches?

3. How did you come to get that answer?

thanks

MOA, Minute of angle, or roughly 1" at 100 yards (exact is 1.047xxxxxxx but for most people it is considered 1" at 100 yards). Think of it as a scale, MOA is 1" larger at every 100 yard increment

Think of a funnel, picture in your mind the taper of 1/8" @ 100 yards, 1/4" at 200 yards, 3/8" at 300 yards... or 1" @100, 2" at 200, 3" @300.........10" @ 1000 yards.
1/8 MOA or 1/8" click represents 1/8" at 100 yards, add 1/8 for every 100 yard increment. Now under 100 yards you divide the value, @50 yards 1 click repesents 1/16", @ 25 yards 1 click represents 1/32".

(Q). To see if you understand this what 1 moa is, in inches at 450 yards what is 1 moa?
(Q 2). What is 3 moa at 400 yards?



(1): 11.6" at 100 yards is roughly 11.6 moa
11.6 x 8 = 92.8 the amount of clicks required. now don't lose count in the 70's.

(2):
So 1/8 moa click value to raise 48" at 200 yards.

Convert the 48" to moa which is 24 moa

1moa = 8 clicks
24moa= 8 clicks x 24..... 192 clicks.

It is easier to count full minutes than clicks, every big number (1,2,3,4...) represents a minute on your scope turret, a full revolution of your scope turret is probably somewhere between 7 and 10 or so. Likely your scope will run out of useful adjustment before reaching 24 minutes. Zeroed at 50 I don't think you will have a full 11.6" of drop at 100 yards, probably somewhere more near 4-7".

All you need to do is take the inches of drop from your zero (not overall drop of the bullets flight path. Many calculators give you total drop as well as drop from zero which might confuse you). Take the first number of the hundreds of yards:

1" for 100
2" for 200
3" for 300

And divide your drop from zero by the inches per yard.

from your 50 yard zero a drop of 11.6 at 100 yards would be 11.6"/1" = 11.6 MOA or certainly close enough for .22 ranges

For your 100 yard zero a drop of 48.8" at 200 yards would be 48.8"/2" = 24.4 MOA.

11.6 MOA would be around 46 clicks at 1/4 MOA
24.4 MOA would be around 98 clicks at 1/4 MOA

If that scope is 1/8 or 1/2 MOA clicks that will further confuse you but I think you might be looking at the wrong drop numbers. 24.4 MOA is way more than it takes me to get to 200 when I shoot MiniMags out of my CZ. Even subsonics I don't think would require quite that much elevation.

I have a Barska 8x32-50 1/8 click value scope

Have you tested the scope to find out what that '1/8 click value' is?
If not, you don't know.

If you want to really get your mind wrapped around this MOA vs. MIL RAD

you could pick up a target shooting game called Long Range Shooting Simulation.

Worked for me. There is a demo program you can download and play for free.

After I played that I just had to have the whole game.
