Thanks, cabezaverde. I've been reloading for around 45 years...pistol, rifle and shotshell. I've read a lot about reloading in that time, and have done a lot of reloading and shooting, but like I said "my memory is a little fuzzy" ... I blame it on my age (70). I tried to give a little history on the H320 powder as I remember it, and I avoid giving load data to people in online forums (but I don't know any load data about H320 because I never had any of that powder.)
