Yes--18 total inches at 500 yds., but it's referred to as 3.6 INCH PER HUNDRED YDS. (IPHY), or 3.4 MOA. So 5x3.6=18", and 5x3.4x1.047=18"
IPHY, MOA, minute, SMOA, Shooter's minute of angle, and milliradian, mrad, mil., etc. is the lingo u sorta' have to get to know when talking long-range. As u gain more experience with it, u'll see how these angular systems of reference fit in/together.
