The Lee Precision 1 oz 12 gauge slug mold is a purpose-built casting tool for shotgunners who want to load custom slugs at a fraction of factory ammunition cost. This mold produces slugs compatible with standard trap hulls, standard wads, and conventional folded crimps—meaning you can cast projectiles that work with your existing reloading setup and don't require exotic components or dedicated equipment. Whether you're a serious trap shooter, a deer hunter who prefers cast lead over factory loads, or a reloader looking to expand your shotgun cartridge options, this mold delivers the speed and accuracy to make slug casting practical and economical.
What sets this slug design apart is the drive key—an exclusive Lee feature that serves dual purpose. The key rotates the slug positively in rifled shotgun barrels for stabilization and consistency, and it also functions as a support rib, allowing you to use standard trap wads without needing a separate support wad or base filler. That simplicity cuts your component costs and speeds your reloading workflow. The slugs perform competitively with high-end factory rifled ammunition; velocity and accuracy meet or exceed expensive commercial loads, making this mold a smart investment if you shoot enough to justify the equipment.
The mold itself is engineered for efficiency. Self-centering automatic core pins speed casting and reduce handling—you're not adjusting alignment by hand with every pour. The package includes the mold, sprue plate, casting handles, and complete instructions with suggested loads to get you started immediately. Load slugs on any standard shotshell reloading press.
