The Lyman Mould Double Cavity 32/40 165gr (manufacturer part number LY-M60247, also identified by Lyman part number 2660247) is a precision-machined reloading tool engineered for casting custom lead bullets. Machined from solid leaded-steel blocks, this mould offers superior heat retention and durability compared to aluminum alternatives. The blocks are heat-treated and cured to oxidize the metal, giving them a distinct blue finish that reduces the break-in time and ensures consistent casting temperatures. Featuring a double-cavity design, this mould allows handloaders to cast two identical bullets simultaneously, significantly increasing reloading efficiency.

Key Features:

• Solid Steel Construction: Machined from premium leaded-steel blocks and heat-treated for long-term structural integrity and optimal heat retention.
• Double Cavity Output: Casts two bullets per pour, doubling production efficiency compared to standard single-cavity moulds.
• Clean Sprue Cuts: Features a hardened steel sprue plate and cutter held tightly by tempered steel spring washers to ensure clean, flat bullet bases.
• Optimised Bullet Profile: Casts bullet design #319247, a 165-grain flat nose bullet with a front crimping groove, designed for stable flight and consistent accuracy.
• Reduced Break-In Time: The pre-treated, oxidized blue finish allows the mould to reach optimal operating conditions faster with fewer discarded initial casts.
