I don't remember seeing any off hand but a call or e-mail to Hodgdon will get you a good answer. I've gotten a number of unpublished loads from them and the return correspondence has been prompt and thorough. I usually like calling as other questions always seem to crop up and it is nice to be able to get immediate feedback. The last time I called I was on the phone for half an hour and ended up invited to shoot prairie dogs with J.B. I had to pass at the time but was told the invite still stands. Maybe this spring...
