I may be North Americas largest consumer of VVN160 (no, not really.)..I had no idea it was killing my rifles for years and years. But then I don't have a borescope...nor would I want to know....but it would be nice to blame my poor shooting on alligator throats. Military's routinely burn double base ball powders, they must not think it's too tough on throats. Short version...I don't know.
VVN160 is single based powder from my understanding, its the VV500 series powders there talking about.
