Trying to get ready for the match this Sunday I am struggling to hit a BIG paper target at 300 yrds shooting AR-5.56
On my new scope, one click equals ¼” at 100yrds. Elevation.
Assuming, and I am not, that I was on center at 100yrds and was shooting 6” low at 200yrds.
How many clicks would I go up?
Or better, what does a click equal in inches at 200yrds and 300yrds?
I am trying to center at 100 and then learn how many clicks required for the longer shots.
If this has been answered before on the forum I failed to find it or search for it correctly.

Every time you double your distance you double your adjustment value. 1/4" @ 100, 1/2" @ 200, ect

If your hitting 6" low at 200 (with a 100y zero). Your 3moa low, so 9 clicks

Zero at 200 and learn your trajectory. Remember the RNT mantra...keep it simple, dickhead!

1/4 MOA clicks are roughly 1/2 inch at 200 yards.

1/2" per click, 6" is 12 clicks

Thanks, trying to keep it simple I did not reply, I went to google and could not figure out the 9 clicks. 12 makes since.

Let me go un-simple again.
6" low at 400yrds would be 6 clicks?
if that is correct;
6" low at 300yrds would be 9 clicks??
Is that correct?
Thanks

my math says yes :D
1 click = 1/4" at 100yrds
1 click = 1/2" at 200yrds
1 click = 3/4" at 300yrds
1 click = 1" at 400yrds

I have no earthly idea why I put 9. Lol. Yes 12. Been trying to cross reference fuel filters all morning and my brain is a bit rattled.

HaHa, I know I'm no math professor, but I was pretty sure about 2 x 6. :lol:

Think of it this way, your clicks equal 1/4" at 100 yards right? so that would be 1/4" x 1 = 1/4" right?

So to make it really simple just take the first number of your yardage 400 yards (4) x 1/4" so your click value would be 1 click equals 1 " at 400 yards and so on, make any sense or did I just confuse the hell out of ya? funny how we overthink the easy stuff.

Probably better of to learn MOA adjustments they are easy as well once you figure them out just think really simple ;) Later,

Inches from POA divided by the quantity of: increments multiplied by hundreds of yards = # of clicks

6 inches low at 300 yards

6/(.25 X 3) = 8

12 inches low at 500 yards

12/(.25 X 5) = 10

7 inches low at 400 yards in glass with 1/8 MOA adjustments

7/(.125 X 4) = 14

Basically what Kirk and others said only different

ETA: Just realized how old this thread is. The formula still works, though.

Thanks guys for renewing the post, I am going to print that info off.
I have got to get to the range and have a math class with my AR.
I will use the above info as cheat sheets.

It will benefit you in the long run to stop thinking in terms of "clicks" and think in terms of MOA or Mils, whatever unit your optic uses. Download a basic ballistic app or program and make yourself a range card with your rifle's dope on it. Try to memorize it, but also tape it to the stock of your rifle for quick reference if you need it.
