In the real world, shooters must keep hold over and hold UNDERS in mind when engaging targets, as trajectory is NOT flat out to zero distance.
NOTE: The 6.5x55mm 140gr SWEDISH is NOT the cartridge the game is based upon, obviously. I believe it's probably modeled closer to the 6.5x39 GRENDEL which is a much lighter round. Obviously, my trajectory data should not be used for this purpose in the game. Just used as an example to illustrate my intent in posting this.
