Question, (and I probably already know the answer): with the demise of H4227, since Hodgdon owns IMR or whatever, can H4227 data be used directly for IMR 4227?
I was given some load data for a 30Herrett barrel I acquired and the best loads were with H4227. But you can only get IMR 4227 now. I know I could/should start low and work up, but I'm just trying to look for a shortcut.
