Are you looking for an AR or single shot/bolt action? For the latter I've just used the book data for the 250 gr Hornady FTX bullet and made sure the seating depth was set for the same case volume as the FTX when using 230 gr FMJ or 250 gr XTP bullets. For reliable feeding in the AR that may make it too short though.

Also, Trail Boss with cheap 230 gr bullets is a lot of fun.
