I've been trying to find data for this cartridge using cast boolits for some time now. I have half a dozen manuals (Accurate #2, Nosler 6th and 7th, Hornady 7th and 9th, and Speer 14th) that list this cartridge with the heaviest bullets weighing 195-220grs. The Lyman manuals ( CastBullet Handbook 4th edition, Reloading Handbook #49, and #50) I have don't list the cartridge at all. The Hodgdon Data Center is of no help either.
The mold I have is the NOE 326471 215gr FN GC design. Does anyone know if the older Lyman cast manuals have data, if so I'll find a used or reproduction copy. I've thought of extrapolating data from what I have for the jacketed loads. Though this is something I have not attempted before. Your thoughts, input, recommendations, and cautions to be taken are appreciated.
