About the Book
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.

Weapon Employment Zone (WEZ) analysis is a method for showing how effective a weapon system is throughout its range of employment in terms of hit percentage. WEZ analysis is explained, and applied throughout the book to show how effectiveness can be improved thru various means.

Accuracy and Precision for Long Range Shooting is written in the same easy to understand language that made Applied Ballistics for Long Range Shooting such an enjoyable and effective book. Long range shooting can be very technical. However, author Bryan Litz, communicates these complex ideas in layman terms, so most average shooters can master the subject with little difficulty.

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
