Precision-machined steel shotgun slug mould from Lyman casts hollow-base Foster-style slugs for 12 gauge reloading. Hardened steel construction with alignment pins ensures consistent results.
This is a serious tool for the reloader who wants to cast quality shotgun slugs at home. Lyman has engineered this mould from solid leaded steel, machined to exacting tolerances and heat-treated for durability.
Superior Materials: The mould body is crafted from hardened steel rather than iron, which cuts break-in time in half and ensures years of reliable service.
Precision Alignment: Hardened steel pins keep the mould halves perfectly aligned, shot after shot, for consistent slug dimensions.
Robust Sprue Plate: The sprue plate is machined from solid steel and ground flat. Tempered steel spring washers and screws hold everything firmly in place under casting pressure.
This mould casts hollow-base Foster-style slugs—the design that requires no rifling and performs reliably in any shotgun barrel. The hollow base provides excellent ballistic stability and energy transfer downrange.
For the serious shotgun hunter or sport shooter, casting your own slugs offers economy and customization. This Lyman mould delivers the precision and durability you need for consistent, quality ammunition.
