Sighting In

You are at the range sighting in and point of impact is 1 inch low.
At 1/4" MOA you would move 4 clicks.

My question is: That same click at 200 yards is equal to what?

Some say it is additive 1/2 " and the others say 1/8". Confused

Howdy. My understanding would be it's 1/2 " a click at 200yds

1/2" like Joe said

A minute of angle at 100yards is 1 inch, therefore 1/4 minute of angle at 100 yards is 1/4 of an inch.
A minute of angle at 200 yards is 2 inches, therefore 1/4 minute of angle at 200 yards is 1/2 inch.
You can extrapilate this on out to however far you want. Very Happy

I agree with the fine responses these folks have given. I would not trust the clicks, but would verify the results at the range shooting actual targets. All the best...

Hi

One M.O.A. at 100 yards is 1.047", actually.

You'll be about 1/4" off at 500 yards with the 1" at 100 yards calculation.

Very Happy

If you aren't going to shoot 500 yards, please disregard. Very Happy

I'm looking to shoot 500 yards, so everyting looks about 1/4" off to me. Nuts

Thanks for clearing that up in my mind. Thatis how I thought it was, but someone whom thought they knew more really didn't. The biggest part about it confusing me is that I have slept since learning things. Age has a lot to do with things. CRS disease. (Can't Remember Stuff)

The best way that I have found to remember click adjustments (for 1/4 minute click anyway) is the number of yards in hundreds over 4. This is the distance that the click moves the POI. It works like this 100 yards=1/4 inch, 200 yards=2/4 inch, 300 yards= 3/4 inch, 400 yards=4/4 inch, etc. You can continue out as far with this formula as you want, just like mikekuzara said.

Remember that this formula works the same way as you get closer. At 50 yards 1 click only moves the POI 1/8 inch, and at 25 yards 1 click will only move the POI 1/16 of an inch. I found this out the hard way a long time ago when I was trying to get my rifle zeroed at 25 yards. It took me a long time to figure out why it was taking so many clicks to move the POI to where I wanted it.

You need to know the value of a 1/4" click at 100. It might be more or less than .25". The only way to know is shoot at the target and 'box' your shots. Aim at the center of the target and fire a shot, move the windage 4 clicks right and shoot, move the elevation up 4 clicks and shoot, move the windage left 4 clicks and shoot, then move the elevation down 4 clicks and shoot. That will give you two important pieces of information. The repeatability of your scope and the true distance of 4 clicks adjustment. Divide by 4 and you have true click value. The results are more accurate the more times you shoot the box. Rarely does a 1/4" click equal 0.25".

I've never run into a good quality scope (Leupold, Burris, Weaver, high end Bushnell or some of the high buck Euro scopes) that have not been right on with the MOA movement of the clicks that the factory claims. Tascos and other low buck scopes are a whole different story. I have seen some that will not repeat click movements, and then again I have seen others that work really well. I have run into some scopes that have been .5 moa click adjustment and some of the Euro scopes are even .33 moa adjustable. This might account for what popgun is talking about with the movements being off.

If you're unsure about the movement that your scope has use the method that popgun mentions and it will sure tell you what the movement of the scope is. It is also a great way to get confidence in the click adjustment of your scope and to ensure the repeatability of the clicks. I have shot at what I thought to be 100 yard ranges that were actually 10 yards or so short or long and this has caused the click movements to be slightly off so be sure that you are real close to 100 yards to make sure of the click adjustment accuracy.
