How long does Black Powder and caps last?
Around my house about 6 months.
How long does substitutes last?
Around my house a bout 2 months longer than real Black powder or until I can order more...
Seriously, if stored properly it's good for many years.
I had a jug of Pyrodex R for about 12 years then used it up recently and had no issues. Stored in a cool dry place the whole time.
Real BP doesn't stay around long enough for me to speak from personal experience on that point.
