My current load is a 200 grain hard cast RNFP and HP 38. Good results. the flat point is the choice, because we load 45 ACP and 45 LC and wanted a bullet that would work in both. The HP 38 was bought at a gun show in an 8# box for $50 simply because it was cheap and worked in several other cartridges. It has worked really well in the 45 ACP, 38 Special, and 9 mm parabellum. BTW, HP 38 is the same as WW231.
