[QUOTE="Mikecr, post: 207066, member: 1521"] My Exbals must be older versions than described because mine do not calc spindrift or coriolis. There are no inputs such as lattitude or twist direction in mine. A Varmint Hunters mag has a write-up from Pejsa defining coriolis as around 1moa at 1kyd depending on various things. It can be more or less. He sums errors like this up as insignificant for similar reasons as Perry. But all the insignicants certainly add up, and I worry about ballistic software providers who generalize 1moa errors.. Seems like they're in the wrong business. [/QUOTE]
