If you don't like trig, please don't read this!
Mk1,
That's an interesting take, but I was just doing the trig and the numbers fall out. Here's how it goes, at least as far as I figure it:
1 MOA @ 100 yds = tan (1/60)*3600 = 1.04719758 inches
2 MOA @ 100 yds = tan (2/60)*3600 = 2.09439534 inches
Note that we are already seeing how 2 MOA is actually a little more than exactly twice 1 MOA at 100 yds, in this case it's 2.00000017 times bigger.
Now, I know what you all are thinking, who cares!? What difference does a factor of 0.00000017 make?!!?
Just hold on and see where this goes at larger angles...
100 MOA @ 100 yds = tan (10/60)*3600 = 104.74930166 inches
This value is not 100x bigger, but is actually 100.0282x bigger. Error's getting more significant now!
Now just for fun, let's look at 5399 MOA. What's that you say? It's still going to be somewhere around 5399 inches at 100 yards? Let's see...
5399 MOA @ 100 yds = tan (5399/60)*3600 = 12375888 inches o
or ~ 195 miles!!! 5399 MOA isn't even *close* to 5399 inches at 100 yards!
Ha ha!
P.S.
You can see where this is going, 5399 MOA is almost 90 degrees, hence my earlier statement.
