I just bought a new rifle, and was wondering about moly and film coated bullets. I've read that coated bullets will extend the life of the barrel andaid accuracy. I've also read that moly coatings will "cook" onto the inside of the barrel and destroy accuracy. Can anyone back up either claim? Also, if moly coatings really are detrimental, can the same be said for bullets with coatings like Winchester's Lubalox? Thanks in advance.
