I have ver 5 and plugged in 10,000 yds and it stopped at 7,200 yds stating that
"Your bullet/velocity combination is inconsistent with your maximum range."
BTW I is used a .308 cal, 200gn Accubond at 3200fps and sighted in at 100yds.
At 7,200 yds that would be 148,173.62 inches of drop,
Think they make a rail for a scope mount to "help"??
Most ballistic programs I ran across go out past 1000 yds.
