I do have a couple of questions, Will having a MRAD based system throw the sighting in of my scope off? I have a MOA mentality as that is what I learned on. Will I be able to sight in my scope as accurately with MRAD as using an MOA based sytem of clicks which is 1/4" clicks? Is there a list of known/approx target sizes (deer 18", man groin to head 39") What is the best way to make a drop chart? trajectory chart? Dope card? I am sure there will be more questions to come.
