In preparation for the 4th of July and some noise making, I pulled out my last can of 1f powder and a buddy asked me how old it is. He pointed out that is says Hogdon's Black Powder, Made in Scotland. I really don't recall how old it may be. I got 5 cans of 1f yrs back when I purchased a 75 cal. yacht race cannon. Seems to work just fine.
