Maths question for someone with brains ?

Happy Easter all !

The question is this-

I have my rifle zeroed at 100 meters.

If I dial 20 moa up, how many inches should the group move up at 100 M ?

My brain is hurting trying to work this out !

Remember to convert the yards to meters.

Cheers

Check my math

1.047 / 100= .01047 That is how many MOA per yard
100 meters= 109.36133 yards
so there is .01047*109.36133=1.145 moa Per 100 meters

20 moa * 1.145= 22.9 inches

That is my guess! it seems close in my book but who knows.

I'm comming out with 22.91"

Using the conversion numbers of 109.4 yards per 100 meters and 1.047"= 1MOA

I was in too much of a hurry to show it after I did it on paper -> but I lost the race anyway lol. Besides, History is my specialty not math (got sick of the theroms, postulets, and other things ;) )
