applying MOA to quarry/targets

[skany]

Hi guys

 

Being a bit of newb when it comes to longish range stuff how do u guys go about using MOA readouts off balistic software & aplying it to your quary?

 

I have a drop chart on my 22-250 which gives me a range then "clicks" to adjust !

 

Now i know the very basics of MOA ie 1 1/4 click at 100 is 1/2@ 200 ect but it seems more hassel then 350 yds is 5clicks?

 

Can anyone make it simpler for me:-)

 

Cheers in advance guys

Very Simply:

 

 

1 MOA = 1" at 100 yards

 

1 MOA = 2" at 200 yds

 

1 MOA = 3" at 300 yds

 

1 MOA = 4" at 400 yds

 

1 MOA = 5" at 500 yds

 

So if your bullet is dropping 6 inches at 300 yds you dial in 2 MOA on the scope

 

If your bullet is dropping 6 inches at 400 yards you dial in 1.5 MOA

 

 

Etc, etc etc etc etc

 

You need to know your drop - EXACTLY

 

You need to know what ajustment your turrets are (1\4 MOA or 1/6 or 1/8)

 

And most important of all, you need to know EXACTLY how far the target is away.

hi skany

 

just to add on to what ronin has said,and lets take it your scope moves 1/4 (4 clicks a inch)

 

if exbal says to add 7.75 MOA (31 clicks) up this means you move your scope to number 7 and 3 clicks,

all so if your scope is calibrated in 1/4 clicks(4 clicks a inch) then 1 click will be shown as .25 MOA

and 2 x 1/4 = 1/2" is shown as .50 MOA

and 3 x 1/4 is shown as .75 MOA

and 4 x 1/4 is shown as 1.0 MOA

 

if you are happy with clicks then on exbal you can tell it to work it out in clicks as well, but it is much faster to run on MOA as you don't have to count every individual click on to your scope.

 

hope i have explained it correctly

For £4.50 this is good value for money and explains things well.

Ya know?

The more I learn about MOA the more I think what a f*cked up way of doing things.

It is generally accepted that 1 in at 100yrds is 1 MOA.

But it isnt.

It is 1.047 like in the link Col48 lists.

Now 1.047 doesnt sound like a whole lot of differance from an inch.

But believe it or not....It is a 5% error.
