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
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
Wind Sensor Array design
Medium and big game hunting
Military and tactical shooting
Ever wonder how much spin drift, Coriolis affect, or using G1 vs. G7 BC's affect
your chances of hitting a target? In Chapter 10 for example, you'll learn that ignoring
spin drift in ballistic calculations reduces hit percentage on a 10" target from
21% to 15% at 900 yards for a specified environment and cartridge.
In Chapter 6, you can see that reducing muzzle velocity variation from 20 fps Standard
Deviation (SD) to 10 fps SD improves hit percentage on a 5" circle at 500 yards from
83% to 93%. These are just two brief examples of the types of analysis used throughout
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.
