Now thats coollight bulb. Where can I find these kind of math? That is a hugh differance. Idont understand, or how they came up with minute as a math turm? Can someone rec. a book or mag that can explain these terms in use? Thanks Bill Maylor.
Eaglet I found an easier way to deal with the .047". Say your target is 18" and you get a reading of 2 moa. 18 divided by 2=900 yards. Now subtract 5 yards for every 100 yards, in this case 9x5 =40. So you say 900-40=860 yards. If you say
17.19198 divided by 2 you come up with 859.599 yards. Thats pretty close huh? This is what I like about the moa system, I can do all the math in my head and for me 3.6 inches is just hard to deal with.

Thanks Eaglet, 9x5 does equal 45light bulb, not 40 I've been going a little stir crazy today, been pacing around the house because of Faye(the storm, not my wife).It has rained all day here. I agree with you on using a range finder instead of using the reticle also, I only use a reticle for ranging on non living targets.That's funny!For reticle ranging to work you have to know the exact size of the target. Animals are constantly moving and standing at awkward angles which also makes it hard to use at extended distances.Plus it's a lot of fun using it.

Good luck to you!Thanks guys, this is a great start. The deer I hunt, on the wall mesured 16+- on the mount. Deer in NW FL. are not as big or as deep as some other states. I would like to see one 18+, and if I do I hope I dont miss. So I starting with 16" or 15.281757 as MOA target size. I mighthave to duck tape a calulator to my gun stock. So let the fun begin. Bill Maylor.
I think MOA math is easier for ranging. Just take the size of target and divide by the number of MOA's it's subtends then multiply by 100.
So say you see a mule deer, which average 18" from bottom of chest to top of back, and this measures 3.7 MOA's in your scope. Divide 18 by 3.7. You get 4.86. Your range is 486 yards. Of course, the farther the animal, the less accurate it becomes. If your rangefinder is forgotten back in the truck, this method would work in a pinch.
If you have a good drop chart and rangefinder... then I think both work equally well.
