Hey guys,

New shooter and trying to learn all I can. I have 3 trips to the range under my belt and I’m confused with adjusting my scope.

Tikka T3x in .223. I have a Vortex Eagle Strike 4-24x50 in the ERB MOA reticle. Each click is .25 MOA

Zero’d at 100 yards.

When shooting at 200 yards I can hold over at 2.5 MOA on the reticle. Works like a charm. But when I try to adjust the elevation on the dial, so I can use th center if th crosshairs, I don’t even hit close to the target I’m trying to hit (I hit paper, but not even close). I’m moving the elevation dial up 10 clicks (.25 MOA per click) equaling 2.5 MOA, right? Or am I not adjusting the elevation knob correctly?
 
How far out is the impact when scope dialed?

From the Vortex pic, the first line down at 24X should be 2moa. Assume you are going 1 1/2 lines "up" to hit?

Jerry, you’ve been a big help. I just loaded up my gear and I’m ready to hit the range in the AM to do another round of testing. I’ll report back with exactly what happens. I’m a bit foggy on the exact results from today (my memory is fading with age haha)

If you are moving up 10 clicks you will move the point of impact 2.5 MOA at 100,
Your 10 clicks will bring you up 5 MOA at 200!

Here's your answer.

Remember MOA is an angular measurement, so MOA at 100 yds is approx. 1", MOA at 200 yds, approx. 2", at 500 yds, 5", etc.

Good Afternoon

Sorry that is incorrect.

MOA is an angular unit of measure 1moa at 100yrds and 1moa at 1,000yrds are the same. However in inches they differ 1moa at 100yrds is 1inch - 1moa at 1,000yrds is 10inches.

If you put on 2.5moa at 200yrds you have moved 5inches

As to your question do you have the ammo data... using American eagle ammo they use a 55gn bullet at 3240fps (feet per second) using JBM ballistics you should need approx 1.3moa from 100 to 200yrds which is 2.6inches. 1.3moa is 5 clicks

All the best

Yes as above -
4 clicks per inch at 100 yds
2 clicks per inch at 200
1 click per inch at 400
1 click is 2" at 800
1 click is 2.5" at 1000
 
Thanks guys, I just got back in from a morning range session.

Dialed in 4 clicks (1MOA was all that was needed) for 200M and it’s dead on.

Not sure what I was thinking yesterday?

Sorry, you're confusing MOA and inches 2.5 MOA is still the same MOA at all distances but the inch value is different.

Glad it all worked out.... but this is a good excercise anyway.... You are going from a near target to a far target. You raise your scope markings to compensate for drop and you hit.... let's say you used the line that was marked "4" and you are at the correct mag for subtension (applies to SFP.. FFP should have subtension constant through the entire mag range)

At THAT DISTANCE, you needed 4 MOA of extra elevation to hit based on your reticle.... if you now dial 4 moa on your scope turret and aim in the center of the reticle, you should also hit in the same spot.

If not, then you need to figure out where things dont agree..... and why

Bottom line,he was dialing in double what he needed.
That's all I wanted to get through to him.
Thanks to you, and the rest, for repeatedly reminding me of my nomenclature misuse.

You're very welcome....I doubt you will make the same mistake again....:)
