One of you guys put me on to Dixie Gun Works,... and I ordered a bunch of stuff, and one thing was a nipple wrench,... I put some moose milk in the barrel, and put my thumb over the barrell, sloshed it back and forth a few times, then proceeded to swab,.... The insuing gusher of putrid, black/grey gruel, that shot out of the nipple onto the wall behind my work bench was damn near a picasso......Lesson learned!!!!!!
