Thanks for the info Rich. I have a real old Lyman reloading book. The front cover is missing so I don't know which edition it is, but on the back page it refers to Lyman as The Lyman Gun Sight Corp., Middlefield, Conn. So it was printed before we changed to 2 letter state identicifation. It doesn't show any of the powders you listed, but does show Bullseye and Unique loads for the .44 Russian, 250gr bullet. I'm still searching for old loading manuals on-line to see what I can find. I've use to use a lot of HP38. Canyou send me the load data from the book for that? Appreciate it.
