The only issue I am aware of is that most anti-sieze compound are metal based with copper or nickel being the most common. As most shotgun barrels are blued chrom moly steel, there lies the possibilty of dissimiliar metal corrosion. This occurs from galvanic action between the dissimilar metals, and it can be worse with plated metals. Heat tends to accelerated the reaction. I prefer a dry lube like molybdenum disulfide, or regular old fashion choke grease. Thanks DB
