Gentlemen....I have to ask a question along the same lines, I have been using Moose milk for 25 yrs, Flint and Percussion, then one day I decided I would try bore butter in my flint, Mind you, I cleaned the Pan and Frizzen between shots. After the 3 rd shot i had so much lube blown all over my lock it refused to spark, it looked like a tar bomb had gone off inside my pan, and I had never used anything paste like since.
Did I do something wrong, I sure liked the way it loaded, but what a mess. I would like to try Mink oil but I figured the same thing would happen. I didn't think I used too much, so I just thought I would run this by you guys, your combined knowledge is priceless.
