I usually clean the bore on my 50 cal J B mountain rifle, with the breech end in very hot water. Ouse cleaning patches on the jag, to pull hot water up into the bore using pumping action with the ramrod. This works pretty well, but rifling on the JB, is so deep, it’s difficult to ensure lubrication all through the rifling and lands. Anyone have an easier method for the Browning mountain rifle?
