I' ve got what' s probably an overworked question but I have not been able to find any information on the subject, which is; what is Lubalox? I bought some Win. Supreme Ballistic Silvertip ammo and I' m not sure about shooting it in my rifle until I' m sure it won' t screw up accuracy by using copper and the Lubalox together (as is the case with Moly and copper). Winchester does not have any information on it in there catalogs. Thanks for any information, I' m just surprised that Winchester doesn' t assure us of this. Can you clean it completely from your barrel?
