The Nosler 230gr JHP is a new product and I can't find any data for it specifically either. I would imagine you could use data for Nosler's 230gr FMJ interchangeably with it. All the other bullet maker's use the same data for all of their bullets of the same weight and caliber, whether FMJ, JHP, flat point or whatever; they just use a different OAL for each bullet. Nosler doesn't give OAL with their data, just min and max length. Seat them in this range to a length that will function in your gun and not long enough to contact the rifling and you'll be fine. Just start low and work up to find what shoots best in your gun. Accuarate has data online for the Nosler 230gr FMJ. You could also start with published data using a different 230gr jacketed bullet and work up carefully. Of course Nosler's manual would have good data too, probably worth picking one of those up. You can never have too many manuals. A One Book, One Caliber pamphlet for 45 Auto would also include Nosler's, as well as everyone else's, data. Good for easy cross referencing, and cheap too.
