I know this question has probably been posted a thousand times but my brother-in-law brought me some stuff from his deceased uncle storage including these apparently unopened cans of powder. Now I'm not sure just how old they are, but it's been a long time since IMR 4320 was 3.40 a can. I'm wondering if it's safe to use. I opened the can and it had the sweet smell just like my 3031 does and looked good.
