I just acquired some H320. It is old surplus that was bought in bulk and split up among shooting buddies, dated 12/69. It is good powder, that has been kept in sealed cans inside. The powder looks and smells like it was made yesterday.
I can't find any data on it. I suspect it was a predecessor to H322. I also suspect it was originally made for military 7.62 Nato. I have emailed Hodgen, but haven't received a reply yet.
Does anyone here have experience with it?
I can carefully work it up and figure it out, but hoping someone here knows something, it would save me some time and powder.
Thanks in advance. Dan
