ok i must be an idiot but i thought min. of angle was the same at 25yds or 200 yds. if you are truely talking min. of angle then it is just that. the length of that ark will vary with the distance referance to it.4 clicks at 100 yds is a min of angle and with the scope in question it is about 1" those same 4 clicks at 200 yds is also a minute of angle but because the length of the radius is longer so the arc length is longer. or do i not understand any of this??

Minute is a word to describe a small amount of angle as in "Degrees, Minutes, seconds" Kind of like "Yards, Feet, Inch" 1 minute of angle is 1 inch at 100 yards or 1/4" @ 25, 1/2" @ 50, 3/4" @ 75, 1" @ 100, 1 1/4" @ 125, etc....so if you were to travel across the ocean for a distance of lets say 2000 miles and when you plotted your course you made a mistake of 1 minute then you would be off of your destination by about 55 miles. I think that is right. My math aint too good. Hope this helps.

Your right, minute of angle or one 60th of one degree is the same number of scope turret clicks at 10yrds or 200 yrds. to infinity.

Minute of angle (moa) is indifferent to distance. One moa is approximately 0.5 inch at 50 yards, 1 inch at 100 yards, 2 inches at 200 yards, etc. So, if you have 1/4 minute per click sights, it will take 4 clicks to move the poi one moa at any distance. At 100yards, for example, each click will move the poi 0.25 inch, or 4 clicks will move it 1 inch. At 50 yards, each click will move the poi 0.125 inch or 4 clicks will move the poi 0.5 inch.

what happens is folks start to confuse min. of angle with a particular arc length they are trying to achieve. it sounds to me Will Munny was trying to find out how many clicks it would take that scope to get 1" at 200 yds. 1" at 200 yds is not a min of angle but about .5 min of angle or theres about.

If one click is 1/4 moa:

25 yds 4 clicks=1 moa = 1/4 inch

50 yds 4 clicks=1 moa = 1/2 inch

100 yds 4 clicks=1 moa = 1 inch

200 yds 4 clicks=1 moa = 2 inches

300 yds 4 clicks=1 moa = 3 inches.

25yrds 16 clicks=1" app.
50yrds 8 clicks=1" app.
100yrds 4 clicks=1" app.
200yrds 2 clicks=1" app.
300yrds 1 click=1" app.

If we round off MOA to about 1 inch, then at any distance, you are going to have to adjust the scope for 4 clicks, assuming that you are using MOA, not inces, and that your scope has 1/4 clicks.

Well, an inch has no meaning in relation to MOA without a distance. 1 inch at 100 yards (approximately).

esldude is correct. moa is 1 inch at 100 yards.

Shootnut is also correct. Thats why long range scopes quite often have 1/2 moa. My 36X42 rimfire target scope has 1/8 moa. At 50 yards it takes 16 clicks to move the POI 1 inch.

MOA can be difficult to understand. I wasnt really talking about MOA, I was talking in laymans terms, the relationship between the number of clicks at a given distance needed to move POI 1". Which is what I thought the original post was trying to ask.

How many times from the muzzle end of the barrel do you run your brass bore brush through dry per MOA?

JUST KIDDING!!!!

yah, your right. I meant assuming 1 MOA is 1 inch at 100 yards

Which then would be 2 inches at 200, 1/2 inch at 50, 10 inches at 1000, and so on.,
