That mould is designed for the Austrian 1895 Steyr straight pull which has a .329 bore.
Lee also make custom 245gn that casts .326 for long throated Mausers

I ordered one last February through Midsouth and am still waiting

I see Lee has a 8x56 mold that cast .329 (C329-205-1R)

I am lucky that my Turk was rebarreled by them before they put it away so I have a tight bore and in excellent shape also. For you that have them over size bores maybe this mold is the ticket.
