Beluebow,
I have a recommendation for you. I believe that you will save yourself a lot of confusion if you disreguard everything but MOA readings. Start learning to read everything in MOA. I teach long range hunting classes and I see the same things over and over with newer students. They lose count of clicks above about 30 or so, they write down inches of drop and try to convert to MOA in their head and they read to many sniper books ( I read many also and there is alot of good info in them ) and apply everything in them to LR hunting. "I want to use the counting of clicks because I can hear them if I can't read the numbers in low light". The planet that I come from we don't get in much night hunting.
Your scope is caliberated in MOA, learn to dial to the moa number on the scope and + a few clicks to make up the fraction of an MOA. You will find this to be much faster in the field, user friendly and less prone to mistakes.
