| Heard all sorts of definitions from people that I don't trust or could'nt understand. Back to the basics please. |

so that means if I'm looking through a 6 moa reticle on a EOTech if my target height is the same height at the reticle then the tatget is 600 yards and if the target height is from the center dot to the top of the reticle then the target is 300 yards, so on??????? Bare with me, I'm learning. |

Let's say you shoot 10 shots into a target at 100 yards, those shots ended up in a group 3 inches big- that's 3 MOA. Let's say you shot 10 shots at a target 300 yards away, those shots ended up in a group 9 inches big- that's still 3 MOA. It all goes back to 1" at 100 yards equalling 1 MOA. So 3 inches at 300 yards would be 1 MOA, 10 inches at 1,000 yards would still be 1 MOA. 20" at 1,000 yards would be 2 MOA. |
7 - here is how you can use your retical to your advantage: You know the dot is 6 MOA Your know an IPSC target is 18" at the shoulder If your reticial is 1/3 of the width of the target , you know you are @ 100 yrds away. If the spatial ratio of your retical to the target becomes such that the retical is greater than the 1/3 relationship to the target - you are farther away. Obviously the converse is true as well. Learn to split your retical up into fractions. Fractionalize the ret to correct for wind, elevation, bullet drop, movement, and distance. You can also think of your retical - a 6 MOA dot - as a 1.667 MIL - just depends on what you prefer. Main thing, have an idea of the drop (in inches) based on your gun and your load, know the effects of a 10mph wind on your load out of your gun (be able to fractionalize this) and use either the MIL and/or MOA scale inorder to be able to effectively determine holdovers and hold offs or adjustments. Good luck |

dexadine.com/WhatMOA.htm That explains much better. Just stick with (one) MOA = 1" @ 100 yards.  Every 100 yards, increase by 1". So MOA at 200 yards would be 2". MOA at 600 would be 6". If you buy an Aimpoint with a 4 MOA dot, that dot would cover 4" @ 100 yards. It would cover 8" at 200 yards. Almost everything is guaged by the 100 yard mark, since a single MOA, or "MOA" is 1" @ 100, if you have a larger measurement, say for a reticle or a group, or an orange sticker target dot, you specify its size based on MOA. It is mainly for clarification. What if Aimpoint said they had a 4" dot. What does that mean? 4" where and what? They could say they have a 4" dot at 100 yards. Then another company could say their dot is 2" at 50 yards. That just leads to confusion for many people. Some people will think the dot sizes are different, when in fact they are the same. MOA relates everything based on 1" @ 100 yards. |
