Well, I figured out that Mils to MOA thanks to the help of you on this board and I thank you very much for that. Now my next question concerns the drop compensator. What bullet weight and muzzle velocity is required to work propperly with the drop compensator? I know that with the Leupold Mk4 M-3 scopes it has to be a 168 grain bullet with a muzzle velocity of 2600 fps. Anybody know what the requirements are on this Chinese scope? BTW, it's the .308 version instead of the original 7.62X54R. Did they account for that in the scope or would that scope still be set up for the original round?
