[QUOTE="Jeff In TX, post: 36164, member: 1522"] On the first run through I've found some screwy things. At 700 yards, the program tracks pretty well with my actual shooting results. However, if I change from 50 to 100 yard increments, my data changes from the orginal out put data. Here's my input data Velocity = 2794 Bullet weight = 168 Bullet BC = .505 Start Distance = 100 yards Increments = 50 and then change to 100 Altitude 500 and then change to 800 Temp = 85 Scope Height = 2.1 Zero range = 100 wind = 0 Target velocity = 0 Keeping all input data the same except the increments and altitude. Example: 800 feet altitude at 50 yard increments my 1000 yard Path in inches is -321.4 When I change to 100 yard increments it changes to -317.8 This seems to happen when I use 800 ft elevation. If I go back to say 500 feet it works fine. Doesn't make any sense to me. The program is also set up for READ ONLY so I can't play with the formulas... yet, just give me some time.
