i was wondering what is a good formula to help with how to use the mils in a scope, now i know this is a dumbass question but i am new to using mildot scopes and have always guessed where to shoot and then would adjust from there but i have a leupold mark 4 scope mildot 1/4 moa but cant seem to find a good formula to use to range out my targets then dope it out on the scope any help would be much appreciated, before i would just mark down in a data book where the hit was and adjust my scope from there but i want to advance and know how to range and dope out my target.
