Genelang,

A friend, who is a WBTS artifact collector and M/L rifle shooter, found an unexploded cannonball years ago. He opened it and salvaged the powder contained therein. It was several feet deep so should have been kept cool. It was greyish in color. He loaded a flintlock with it and fired it, but it seemed weak. Doesn't prove anything, but interesting nonetheless.
