[QUOTE="dennishoddy, post: 3365017, member: 5412"] I wonder what caused that 4350 to turn to dust? Moisture? Back when I started reloading in 1980, IMR 4350 was my go to powder for 30-06. Still have a couple partial tins of it. At that time, a lot of that powder was surplus from WWII that had been reblended from other powders. Once it was gone Hodgen started manufacturing of the new powder we have now. For historical purposes, the IMR stands for Improved Military Rifle.
