Surprised no chemist / black powder shooter has not weighed in with what ingredient would make oil soluble with water.
I tried some groups with Pinesol & windshield washer fluid mix, about 30:70. I find this particular rifle doesn't care and the POI is the same with all lubes, from plain spit toLHV. Might be something to do with the bore size?The group is actually 1.105", due to the smaller ball used.
