I have a 58 cal. Pedersoli. It will shoot those conicals. Pedersoli makes some really nice guns. They are expensive but they are top of the line. Many of their guns are designed for conicals with a 1:24 twist and some ,like my double barrel 58 are 1:48 Theyare available in the states from Cherry's, Dixie and other places. so parts if ever needed aren't hard to find
