, looking for input on lifespan, etc. Anything besides smell test to tell viability? Thank you in advance.
 
If it smells like normal gunpowder then it's probably fine. I've been shooting a bunch of 30 year old IMR 4320 in my 223 that I picked up at the beginning of Covid for $10/lb.

The steel targets don't seem to ring any different.
