While I don't shoot jacketed in large bore revolvers, highly recommend Lehigh's 300gr solid copper Extreme Penetrators and their 330gr WFN with N110, H110/296 and 2400 for the Bisley .480s.
335gr, 355, 375 and 410gr cast all shoot well also.
As usual, work up your loads per your book and data resources for best performance.
