Several manufacturers have available molds for Minié balls with the hollow base insert integral with one of the mold halves. It seems reasonable that manufacturers or custom mold makers would have available molds for hollow pointed bullets where the hollow point insert would also be integral with a mold half. All that is necessary is for hollow pointed bullets to be cast nose-first.
Having just pontificated on the ease of achieving the result I want, please identify manufacturers who have such easy-to-use hollow point molds available.
