Murphy strikes on the eve of Pennsylvania's deer season. While preparing my gear, I discovered my powder horn developed a fully open, longitudinal crack that extends for half the horn's length. (It was fine just a week ago when I last shot at the range. Cause?!?!) So it looks like tomorrow, I'll be pouring BP from the big red can instead of the horn. Any suggestions for a repair? I'm thinking that 2-ton epoxy and a couple of quick clamps would work.
