I like the concept of Bore Butter and I have generally had good luck using it as a patch lube. Today, after a shoot I found my later cleaning patches coming out dirty grey-brown. Not rust, but lots of residual stuff and I went through about 20-30 patches, all coming up suspicious. Even alcohol patches continued to come up dirty until I finally got down to steel. This time I finished with pure mineral oil before putting it away.
I realize I am opening a can of annelids (worms) but what are opinions on Bore Butter?
