Has anyone "out there" ever loaded the .455 Webley Mark VI with an as-cast Lyman 454613 boolit? I just got an uncut Mark VI, a want to reload for it but the old RCBS .455 molds are unobtanium. I bought the Lyman mold off ebay, having read somwhere, someone had success with a Mark VI, but in retrospect think the shank may be too long for that short Webley case. Any thoughts or experience out there?
