There's a lot of good information available on long range shooting which explains how to correct trajectories for drop, wind deflection, etc. This book takes it a step further and discusses how various uncertainties affect your hit percentage.
This new edition of Bryan Litz's comprehensive volume on long-range ballistics includes two additional chapters covering extended long-range shooting and monolithic bullets. Nearly every other chapter has been updated; the chapter on wind deflection has almost doubled in size. Bryan provides experimentally determined ballistic coefficient data for over 235 long-range bullets. Bryan thoroughly explains the fundamentals of longrange ballistics to help anyone wishing to become an accomplished long-range shooter.
