That happened to a buddy of mine at deer camp. Camping in a state park open to deer hunting. We were camping in teepees, wall tents and tin teepees. Him and His son were in a wall tent. His son was moving his long rifle and was laying it on a cot when the cock snagged on a blanket and released it causing sparks and a big hole in the side of the tent, it was smokey in there for awhile
. The ball traveled at a horizontal angle as can be imagined. We don't know where the ball ended up but there were a lot of campers around and no one was hurt. Most of them came a running thinking someone got shot. Again no powder in the pan. One can never be too careful.
