shelf life

[Tommy.Gun]

Of gun powder?

 

[Mannlicher]

are you talking black powder, or smokeless?

Black powder can last a long time. I remember as a child setting off some that we found way back in a coal mine in SW Virginia, it worked fine.

I don't think Smokeless poweder has been around long enough to really tell about shelf life. I know if it has been stored properly, stuff made back around the turn of the century (1900, not 2000) still works fine.

smokeless,

I have just finished a 30 year old can of unique.

Rule of thumb on smokeless powder: If it does NOT smell acrid (sharp and harsh or unpleasantly pungent, irritating or deeply bitter) it is ok to use.

I've loaded ammunition with powder that was 20 years old. It worked just fine.
