Lyman Super Moly Bore Cream is applied directly to the bore of a firearm. Brushed into the pores of the rifling, it smoothes and polishes the surface to a black, shiny, friction-free finish. This Super Moly Bore Conditioner Cream reduces bore fouling and increases barrel life as well as accuracy. Great with plain jacketed bullets and even better when used with molly coated for total performance.
