Accuracy & Precision for Long Range Shooting by Brian Litz

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.

The book is broken into 3 parts: Precision, Accuracy, and WEZ analysis.

Part 1 focuses on Precision, which explores how hit percentage is affected by variables affecting group size, including:

• Muzzle velocity variation 
• Range estimation error 
• Wind estimation error, and 
• Inherent rifle precision 

Part 2 focuses on Accuracy, which is how well the group is centered around the aim point. Chapters in the Accuracy section include:

• Leveling your sights 
• Trajectory modeling 
• Secondary trajectory effects 
• Calibrating ballistic solutions, and 
• Live fire verification 

Part 3 focuses on Weapon Employment Zone (WEZ) analysis including:

• 300 Winchester Magnum 
• 300 Win Mag vs. .338 Lapua Mag 
• Score Shooting 
• Wind Sensor Array design 
• Varmint hunting 
• Medium and big game hunting 
• Military and tactical shooting
