I don't like to hear/read someone is using a manual 30 years old with current production powder!! I have 5 or 6 pounds of H4831 that is 20 years old, I am using a Hodgdon Data manual #6 (1992) as a guide for this lot of powder. With current production powder I would use current data from the powder manufacture or the bullet manufacture only! William
