Anyone cast/reload their own shotshell slugs? I recently bought a used MEC 600 Jr to try out shotshell reloading. I have a Lee 1 ounce slug mold which casts hollow slugs made for loading in lead shotshell wads. How well do these work? Anyone ever try the larger NEI cast slugs? What diameter should I be looking at if i decide to try out an NEI slug in a mossberg rifled slug barrel? NEI has .732", .734", and .740" slug molds available. I am not really interested in trying sabot slugs right now. Thanks.
