[QUOTE="green 788, post: 712414, member: 3781"] The drop chart cannot anticipate the point at which your bullet crosses the line of sight, therefore it doesn't know with certainty whether the bullet is still rising at 100 yards or whether it has begun its descent. The chart assumes that the bullet has begun its descent by the 100 yard point, falling back through the line of sight at or very near 100 yards (after first rising thru the line of sight sometime around 40 to 60 yards or so). This is why you have to "true" your chart. You'll likely not find a perfect program that gives you accurate drops for all ranges... What you can do is set your zero for 200 yards, by which time the bullet is definitely falling, and plot your drops from there on out. Then make some notes on the data card indicating your 100 yard to 175 yard "hold under"... Dan [/QUOTE]
