I checked the 1/2 can I have, it still looks good, I've had it since 1996 the 50th anniversary of Hodgdon Powder Company. It has an $11.50 price tag. I would give it a try to see if it's any good but all I have is a Flintlock. O.K. guys I just took it out back an tried it, just a half a palm full, (no I did not have it in my palm when I tried it) Well, it went off like a rocket
. But whether or not it's still full strength is another matter, but the way it went off I would have to say yes, it's 16 to 17 years old. I wish I still had my .54 caplock Renegade to try it.
