The Lee Double Cavity Mold - .311 Round Ball W/Handles is a precision reloading tool designed for shooters who cast their own lead projectiles for historical firearms, muzzleloaders, and antique weapons. Whether you're a competitive black powder shooter, historical reenactor, or serious collector maintaining period-correct ammunition, this mold delivers consistent, quality-cast balls that match exacting bore specifications. The double cavity design increases production efficiency, allowing experienced reloaders to generate multiple balls per cycle while maintaining uniformity that affects velocity consistency and accuracy downrange.
Engineered with two precise cavities, the Lee Double Cavity Mold produces .311-diameter round balls weighing 45.16 grains each—a specification critical for period firearms and blackpowder applications where bore fit directly influences performance. The integrated handles provide superior control during the pouring process, reducing hand fatigue during extended casting sessions and minimizing spillage of molten lead. Lee's aluminum construction balances thermal conductivity for efficient cooling cycles with durability across hundreds of production runs, while the cavity design ensures uniform ball weight variation stays within industry-standard tolerance bands essential for consistent ballistic performance.
This mold serves competitive and recreational shooters who reload for Civil War-era rifles, flintlock muskets, smoothbore fowlers, and other traditional arms where .311-inch balls are specification. Law enforcement firearms instructors and military historical units also rely on consistent ammunition production for training and demonstration. The handles allow safe operation in workshop environments and reduce the learning curve for newcomers to lead casting. Compatibility extends across all platforms accepting .311-caliber projectiles; pair with a lead melting pot, casting ladle, and cooling tray for a complete production setup.
