My grandfather had a ML over his fireplace for about 30 years. One day he built a good fire. While stiring the fire up, a lot of sparks drifted around. Next thing we new, BOOM!. He now had a big hole in the wall, all the way through the roof. He never new it was loaded. Rifle jumped off the wall and broke the stock. I don't know what he did with it then. The rifle was traded to him for something when he lived in Kansas. He moved to Colorado during the Depression and built the house, hung the rifle up when the house was finished. The big BANG occured in the early 60's. The rifle was a full stock flinter but I don't remember anymore about it. It was always out of my reach. Sure am glad. Rifle hung with the lock side showing.
