I found this app to be very useful when I was out hunting with an unfamiliar rifle over long distances. One thing that would be nice would be some basic ballistic charts for common military applications. Pre-loaded tables for an M16 shooting 62 gr ball would be great! Obviously you cant have everything in there, but the basics of M16 w/ 55,62,69,75 gr ball. M1/M1903 with M2 ball and match ball. And M14 would be a good start!
Also, most .223 rifles are likely AR15s, which have a 2.5" sight base. When a .223 caliber is selected with a govt profile bullet, perhaps make the default sight hight be 2.5" rather than 1.5"?
