I had a can of Dupont FG with a $2.50 price on it. I bought it back in the mid 60's for a .75 cal cannon, that my brother and I built the carriage for, the barrel came from DGW for $15. We dug it out 8 yrs ago when we were clearing out our parents old house. The powder was still good and we even fired the cannon with some 30+yr old cannon fuse.
