RE: Ammunition concern....
Aparently Winchester uses two different types of coatings.
Lubalox is only used on the Balistic silvertip and the molly (previous post) is used on the failsafe and partition gold.
I still think the salesman is full of crap. I don't think that Nosler and Winchester both would stake their reputations of a coating that rusts out your barrel.
Here is what Nosler says about the two.
Are Lubalox and Moly the same?
NO, Lubalox (CT Ballistic Tip) is an oxide-based coating, which reduces fouling and allows more shooting between cleanings, also Lubalox does not buildup in the barrel and requires only normal cleaning procedures. Moly (CT Fail Safe & Partition Gold) is a molybdenum disulfide coating which reduces fouling and friction. Moly requires a barrel be conditioned by shooting several rounds after cleaning and special cleaning procedures. Accuracy with non-coated bullets may not be up to par in a Moly conditioned barrel.
