was in a LGS about 6 months ago and was looking at the muzzle loaders on the shelf. there was a old flinter there, I took it down and was checking the bore and yep you guessed it, it had a charge in it. measured the bottom of the bore to the ramrod and it surely had powder under the ball as there was also a mark on the rod. there was a flint on the lock, so it told the owner about it and his response was " it probably wont go off anyway, I'm sure that's why it is still loaded." I offered to pull the ball for him but he said he would get to it. I left it on the counter and haven't been back there since.
