I have some cast bullets lyman mold 420 grain FP with a mix of 20:1 (BHN

I use 24 or 25gr 2400 with very fine accuracy or 13gr of  Unique with reasonable results. I've used these loads with Saeco's 425 gr. spire point, lee's 405 gr - actually 420 gr because I had the solid point version - and a 460 gr lyman flat nose mold that I can't remember the number of. I'm shooting a rolling block in very good shape. Good luck.
