DOWNHILL SHOOTING

Same rules apply for both downhill and uphill shooting

COMPENSATION FOR ANGLE 300 yds * .91 = 273 yds Direct range / Slope distance

To obtain gravity range multiply the direct range by the appropriate multiplier.

X2 + Y2 = R2 X2 = R2 - Y2  Y2 = R2 - X2

Example: Y = 20 yds, R = 100 yds X2 = R2 - Y2 = 1002 - 202 = 9600 = 98
