Right after Dupont changed their powder manufacturing from the U.S. to Canada I had bought a 1lb can of IMR 4320 to try in the 30-06. Only had the can for about 6 months. Powder was made in the U.S.. When I opened the can the lid was rusted, red dust aka rust and the powder had an off smell. Used it to fertilize the grass. Only thing I can figure is that prior to the operation being moved to Canada, not all the steps were followed that should have been. I've had powder that is over 20 years old and still has that solvent smell. And do check my stocks yearly. Not that with the current crazyness I have a large stash of powder. I do shoot cast bullets and depending on the cast bullet, powder charges are less than 55% of a normal load. Frank
