Yep.
Ugly! Ammunition similarly deteriorated has blown up many firearms. I have collected posts throughout the web on blown up guns with old gunpowder/ammunition, but the absolute common factor is, they don't know. Shooters don't know that gunpowder ages and when it gets to a certain level of deterioration, it will blow up your gun, and in bulk, will burn down your house. There is absolutely nothing good about old, deteriorated gunpowder. We need more pictures like that, to combat the cultural ignorance about deteriorated gunpowder.
