MOA question

okay, im still trying to figure this whole thing out. If I sight my gun in at 100 yds, and im shooting,say, 21 inches low at 400 yds, i would turn my scope up 2.1 MOA. That would be 8 or 9 clicks with a scope with a 1/4 moa right?

Re: MOA question

Nope!

21 inches low at 400 yards.

400 yards divide by 100 = 4.

(MOA is angular measure and we base it on 100 yards so you MUST divide yardage by 100 to get to MOA. @ 100 yards 1 moa = 1.047 inches)

21 / 4 = 5.25

You come up 5.25 MOA, 21 "clicks" on a .25 MOA scope.

If the distance were 700 yards and you were 63 inches low the answer you be calculated like this;

700 / 100 = 7

63 / 7 = 9.0 MOA

You'd come up 9.0 MOA or 36 "clicks" on a .25 MOA scope.

Re: MOA question

Moving the decimal point two places does the same as dividing by 100, no math involved, and I'm sure Dave does this in his head too. But, dividing by 100 shows what you are really doing.

If your shot was at 1000 yards, or 10 times as far, your inches divided by 10 like you did would be correct. You were only shooting 4 times as far, so you'd divide by 4.

680 yards would be 6.80 times as far, so you'd divide the inches by 6.8.

Re: MOA question

thanks. hows this, the distance is 564 yards, im 32 inches low. I divide 564 by 100. Then i divide 32 by 5.64 and get 5.67, so id have to adjust 5.67 moa, which is like 22 or 23 clicks. Is that right?

Re: MOA question

Yup!

Now you got it.

Brent's correct, I do the math in my head (that's why I got an ugly head) but show the yardage conversion for illustration.

Re: MOA question

Heres another scenerio. 720 yards, 67 inches low. 67 divided by 7.2=9.3 MOA. thats 37.2 clicks, or 37. Do i have that right?
