Good advice. I will do just that. Thanks.I was gifted some Hodgdon “relics” some years back. They had been in storage for a long time in a nice basement. I have some basically lunch sacks that had some load data and what powder was in it. The newer stuff I received from another source was in quart paint cans. Some was 4895. It looked good and smelled fine, poured some out on a piece of white paper and no dust or deterioration.
I actually shot a couple of the quart cans with no issue and funny stuff.
All of these cans were in round hat boxes. I opened them up a while back and all of them had gassed and rusted clear through the tins.
I would suggest if you want the containers to stay as nice as the look, to dump the powder.
Do as you wish. I had lost some IMR 4198 to similar situations prior to that.
