This book is essentially a detailed Sniper Training manual for use by Military/LE Snipers, Competition shooters, Long Range Hunters, and other enthusiasts. It describes, in detail, methods of range and wind estimation and includes practical exercises to ensure that the reader understands the methods outlined and also has a quick reference guide for the most commonly used equations in this skill set. The book was primarily written for those new to long range shooting however, I hope that even experienced shooters will benefit from the book.
