gjw. I think you have been misinformed, or you have your panties in a crinkle.
We don't use grease to lubricate the bores or the wads, what we do is lubricate the wads in a mixture of beeswax and cooking oil by immersing the wads into hot wax/oil via a deepfat fryer. Just use the wire basket to hold the wads immerse in the hot wax remove to drain off excess and then your good to go.
