strange that lymans "38 special +p" load of 5 grains, is hodgdons "357 magnum loading"

Powders are never the same unless purchased in the same container, and even then may not be the same over time based upon storage conditions, like being subjected to variable temperature and vibratory conditions. Besides that, various lots can be and are made by different chemical companies. In particular is WW231 versus HP38. These two powders are for the same application arena, yes, but that is all you can say for sure via application notes, like from reloading manuals. For example, several large lots of HP38 were made in Scotland, versus the US for many lots of WW231. ... felix

All modern HP38 is the exact same as 231. I confirmed this by talking to Hodgdon themselves. They will tell you the same thing.

Everything I have read says that the powders come from the same hopper and are put into different bottles.

My dad has 231 and HP-38 that has the exact same lot number. So, just different labels from Same lot.
