In the late 1970s, perhaps into the 80s, Shiloh Sharps offered two .54-caliber "Buffalo Slug" wadcutter or "trash can" bullet molds for their 1863 Sharps carbines (and rifles, if these were in production), the larger of the two molds dropping a [nominal] 580-grain wadcutter bullet. Does anyone know where either sample bullets or one of these larger molds can be obtained?
