Ok first of all I'm using a Rem. 700 AAC-SD .308 with a bushnell 10x40 mil/mil tactical. I have been playing with this JBM calculator for the trajectory card for about two hours and I think I have everything else done right but what should I use for the drop units? Should I make it .1 or 1 in mils or should I do it in inches I'm confused. Also, depending on what drop unit I use will the chart give me drop in mils or inches? I'm a noob so I'm trying to get all this down and learn something!
