new this stuff but for my scope one click is 1/8 at 100 yards. so whats it at 200 etc..

i have it sighted in at 100 yards and hav been shooting at that range for a long time but when i shoot at 200 yards i kno my rifle shoots 2 inches low i dont adjust my scope fo it thou and just know to aim 2 inches higher at that range.

so if its 2 inches low at 200 yards how many clicks is that

8, but its not as simple as that. For starts, you should get yourself an appropriate ballistics chart. Lots available on the Internet. Lots of info on the Internet to describe how to go about this too.
 
1 MOA at 100 yds is roughly 1 inch. (1.0472 if you want the exact numbers)

200yds = 2"

300yds = 3" and so on.

1/8 min turrets = 8 clicks per 1 MOA. Since you are 2" low at 200 (or 1 MOA) then you would have to add 8 clicks.

Learn to read the numbers and hash marks on your scope rather than the number of "clicks". If you need to come up 5.5 MOA it is far easier and faster to use the numbers and hash marks than it is to sit and count out 44 clicks.

My scope has 6MOA per revolution so I know if I have to come up 19 minutes I need 3 full revolutions of the turret plus one extra MOA added to reach the 19.

Just for reference....19 MOA would be 152 1/8min "clicks" I could have 10 rounds down range by the time you count out each notch.

I'm going to sum this up for u.

1" = 1moa @ 100m
2" = 1moa @ 200m
And so on
10" = 1moa @ 1000m

See the pattern?

On your scope @ 100m 8 clicks will move ur point of impact 1"
@ 200m - 8 clicks will move u 2"
@ 700m - 8 clicks will move u 7"
See how this works ?
 
MOA in a measurement of ANGLE.

Think of it like a laser pointer... If you aim a laser pointer 1MOA to the right of the center of the target, that laser dot will strike a hair over an inch to the right of center at 100 yards, The distance from center moves by multiples of distance from the laser, so at twice the distance (200 yards) the laser dot will fall twice as far away from center, 3X further away at 300 yds etc.

It also helps to know how accurate your scope really is, so tape a ruler to a board 50 yards away from your scope (100 yards is better IF you can read the numbers) Witht he rifle mounted firmly in place, read how many inces the dot moves with each series of clicks,

At 50 yards, if your scope is 1/8MOA per click, then it should take 8 clicks to move half an inch, one inch at 100, two inches at 200 etc.

ok so 100 yard zero my ballastics chart for my bullet is saying at 400 yards it is -26" low
how do you figure out how many clicks for that?

is there a formula you guys use
Click to expand...

inches * 100
MOA = --------------------------
1.047 * distance in yards


fawk i like how i cant space that out properly :/
 
im using the hornady one nowi got a chart printed out, says the trajectory and then it says come up in MOA. i then changed it all using a calculater to how many clicks. ex.
so say at 400 yards it says -27.1" it says come up 6.5MOA. which i multipled by 8 and got 52 clicks correct?

another 600 yards -93.5" come up 14.9MOA which is 119.2 clicks.. Am i on the right track here?
 
The quick way would be to simple divide drop in inches by the yardage.
In this case 400 yrds is 4 x longer then 100
26" (inches) / 4 = 6.5 MOA

it would be the same for any yardage 700 yards would be 7 x longer then 100 ASSUMING you sighted in at 100.

Remember that a Minute of angle is always the same regardless of the distance you shoot. 1 moa at 100 is 1 moa at 400. The difference is the number of inches it moves at the longer distances. 1 moa is 1 inch at 100 but at 400 yrds 1 moa is 4 inches.

I think this is a great article that explains MOAs and MILs rather well...and it has just enough math to make your head hurt.

Yes 1/8 click scope that would be correct. but i would stay away from clicks. use the numbers on the scope. If your scope at 100 yards has you at 2.5 line adding 6.5 would put you at the 9 line mark.
How many minutes do you have per revolution 6-8-12??
 
yeah im not gonna count the clicks its just easier for me to read cuz i know i got 10 clicks between each number on the turrets. and i got 8 mins per revolution. ill get used to the whole min thing soon enough
 
Do u use a mill-dot scope? You will find milldots easer than clicking all the time.
@400 yards, aim up 2 mills. If ur scope is 10x that will be 28.8".

Distance between 1 milldot at distance

If u remember 3.6"@100 you will see a pattern. Keep adding 3.6" per every 100y distance.

Yard / Inch
100 -- 3.6"
200 -- 7.2"
300 -- 10.8"
400 -- 14.4"
500 -- 18"
600 -- 21.6"
700 -- 25.2"
800 --28.2"
900 --32.4"
1000- 36"

One more thing, if u want to stick with MOA remember that @ 100y there is 3.6 moa between 1 mill.

Ie. If your bullet drop @ 1000y is 36 MOA (360inches) you will aim up 10 milldots because there will be a distance of 36" between dots as we can see in the chart above.



I hope this info helps u shoot better.

Except that 26" at 400 yards is 6.21 moa according to my BlackBerry. There are computers for this, no reason to make approximations on the back of an envelope. 1 moa is 1" at 95.5 yards.
It is only 1 click of a difference, but if you are using a computer to calculate drop, use one that actually outputs 1/4 MOA clicks. I would suggest.

26" /4 / 1.047 = 6.208 MOA / .125 = 50 clicks up

If I were you I would calibrate your clicks. Just because it says 1/8 moa may not be exact.

I did mine by zeroing my rifle at 100 yards.

You need a tall piece of paper. I used cardboard and a strip of paper to have a target over 4 feet high. Place an aim point near the bottom of the paper. Aim at the same point for all the tests.

Shoot a group at you 100 yard zero. Rotate your turret up one full turn. (know how many clicks) and shoot another group. Repeat this.

I did it with my bushnell 6500 2.5-16x50 scope that had 1/4Moa clicks (.250)

After 4 rotations up ("12MOA" or 48 clicks per rotation) I was a little more than 4 feet above my 100 yard zero. I logged and calculated, plotted all of these and was able to figure my clicks on my scope are .268moa per click vs .250 advertised. This makes a big difference when shooting long ranges. I also did the same test using just the windage with the elevation back at the 100 yard zero and the result was the same.

PM me with a email address if you want to see an excel spread sheet with the calculation built in it. It makes it easier to just put in the data. Also I measured with a 100' tape the exact range from the target to the centre of the scope. A few yards will change the click value calculations. Its all just angles. Once calculated you won't have to do it again for that scope.

This is a video shooting at 822 yards done prior to confirming my clicks. I was shooting low. I thought my clicks were .285 per moa from a previous calculation. Later that day I went back to 985 yards using a calculated .268 click based on the observations at 822 yards and was hitting there also.
