I have two old cans of powder. One is IMR 4198 & the other is Alliant Reloader 7. The RL-7 still has a faint acetone smell to it but the 4198 will curl your nose hairs. They are both the same approximate age (20 years old) & have been sitting next to each other in the powder drawer of a steel filing cabinet in an air-conditioned room. There is also some brown dust in the 4198. It could be rust but I'm not sure 'cause the inside of the can still has a shiny steel color. It's probably from the chemical break-down of the powder. Will probably spade it into the soil of my rose bush.
I've got some Lapua 220 Russian brass loaded with that RL-7 for fire-forming into 6mm ARC.
