Just upgraded from Windows ME to XP, and find that my Sierra Infinity program does not work with XP.

What I need to know is the exterior balistics of a .458 dia., 350 g. bullet (B.C. .402) at 2100 M.V. The rifle shoots these 4" high at 100 yards (semi-buck horn sights). Can someone run this in their program and give me the elevations in inches above and below line of sight at 125, 150, 175, 200, 250 and 300 yards.

40 degree temp, 5000' elevation, would do for weather.

Thanks in advance for the help.

Thank you gentlemen.
