The increasing number of firearm owners across the country has highlighted a critical need for accessible, no-nonsense training resources. Seeing this, L. R. Moore III, MSGT. USMC Ret., took his 20 years of military expertise and created Range Master Books LLC. As a Range Master and nine-time Expert Shooter award recipient, he wanted to share the same proven marksmanship techniques that helped him achieve success. His goal was simple: to provide shooters of all backgrounds with the knowledge and structure they need to train effectively and safely.

That mission led to the development of the Marksman Shooting Ledger, a practical tool for tracking shooting progress and refining technique. Using the BRASS shooting method, the book simplifies the process of improving accuracy, helping shooters apply proper fundamentals in real time. Range Master Books LLC is more than just a publisher—it’s a resource for firearm education, safety, and skill development, built on firsthand military training and a passion for responsible gun ownership.
