When asked by my neighbor, (and good friend), why after shooting and cleaning his muzzleloader, the next day he'll get brown patches when running a dry patch? I told him he had the worst thing in his bore... Metal worms... The brown was from them breeding overnight and him smushing them the next day with the patch... :: :bull: We talked about it, something came up and I had to leave before telling him the truth that he wasn't getting his bore dry before oiling... Anyway, a few days later other local muzzleloading shooters started to come in where I work wanting to know about, yes, "Metal Worms"... I finally told my neighbor the truth, and we did have a good laugh. I think he told the whole town??? I can't believe they all believed that???
