Lee Precision core pin SM3527 for 1 oz Slug Mold 90281

Core Pin 1 oz Slug Mold SM3527

The core pin is the pin that forms the internal cavity of the projectile within a bullet mold: without the core pin, the mold would cast a solid body. This is the core pin for the Lee 1 oz shotgun slug mold.

The cavity created by the pin is what defines the final weight and mass distribution of the slug, so the geometry of the part directly affects the casting result. The core pin is also the most exposed component of the mold, as it remains immersed in molten lead with every cast. Lee secures it to the mold with a dedicated shoulder screw (part number BM3265), which must be ordered separately if missing.
