The Lee 12 Gauge 1 oz Slug Mold (Lee part no. 90281) casts a 1-ounce lead slug designed to shoot accurately out of rifled shotgun barrels. Shotgun slug hunters who load their own ammunition use it to cast consistent, sabot-style slugs at a fraction of the cost of premium factory rifled slug loads, without giving up the accuracy those loads are known for.
