At 1000 meters the Mk211 Raufoss Special Purpose .50 caliber round has a 
flight time of 1.65911 seconds with a maximum trajectory drop of 132.2502 
inches.  the bullet will drift 5.87 inches to the right of line of sight 
barrel twist.  Hate to say it, but these are not a concern to snipers since 
this is known information.  It is air temperature, pressure, angle of shot, 
etc., that has to be adjusted for at the time of firing that causes 
headaches.  Every snipers best friend is a scientific calculator.
