SIERRA Reloading Manual 5Th. Edition & V7 Infinity CD #0507

Sierra's INFINITY Exterior Ballistic Computer Software version 7 provides multiple trajectory charts and graphics, point blank range, calculate zero, uphill/downhill shooting, maximum range, minute of angle, profiled wind, improved atmospherics, revised print formats trajectory in mils and more. Easy to use Windows format makes INFINITY extremely user friendly. Bullet library includes all major bullet companies as well as ammunition companies and allows for addition of new and custom bullets. Renowned Sierra Ballistic Consultants Ted Almgren and Dr. Bill McDonald, who have written all Sierra Software since 1970, also wrote INFINITY 7. Both are retired Chief Scientists from a major aerospace company. This program is available in CD-ROM format only. Interface and program architecture design by Rodney Korn. The program does much more than compute bullet trajectories. It contains a feature that computes the effects on the bullet trajectory of variations in firing conditions. For example, you can change altitude of the firing point, and compute the effect on the trajectory. Or you can change a wind condition; or muzzle velocity; or Ballistic Coefficient. In fact, you can change any inputted firing condition or combination of conditions. You can also graph the trajectory variations that result.
