Lyman Load Data Book 30 Caliber

The Lyman Load Data Book 30 Caliber is the reloader's reference standard for precision ammunition development across all .30-caliber rifle cartridges. Whether you're handloading for a .308 Winchester, .300 Win Mag, or .30-06 Springfield, this comprehensive manual provides the authoritative load data necessary for safe, consistent ammunition production. Law enforcement and military personnel who maintain their own ammunition have long relied on Lyman's meticulous testing protocols and cross-indexed data formats to achieve both accuracy and reliability downrange.

This load data book contains detailed powder charge ranges, primer recommendations, bullet weight specifications, and velocity predictions for dozens of powder and projectile combinations in 30-caliber calibers. Each entry is organized by cartridge type and includes minimum and maximum loads with clearly marked pressure thresholds, allowing reloaders to work safely within published SAAMI specifications. The manual's tabular format enables rapid data lookup during progressive reloading sessions, and cross-references between similar cartridges help identify safe starting points when exact load data is unavailable. Lyman's data is derived from ballistic testing conducted in controlled conditions, making it the baseline for reloaders seeking consistency and safety.

Serious reloaders, competitive shooters, and tactical marksmen benefit most from having a dedicated 30-caliber load manual on hand during ammunition production. This reference is particularly valuable for those working with multiple .30-caliber platforms—where load optimization varies significantly between magnum and standard cartridges. Keep this manual at your reloading bench as your primary data source; it pairs seamlessly with modern electronic scales, calipers, and chronographs to ensure every round meets your performance specifications. Essential for anyone committed to ammunition independence and precision performance.
