Didnt we have a whole thread about this recently? This has kind of been prven to be a "wives tale" hasnt it? I personally have shot at least 15k rounds of laquered stiff in the last few years and never had any issues...most I know that have used it can say the same thing.
Plus I dont believe that silver bear is coated.
Not sure about the silver bear, but I will tell you laquered ammo in an AR is not a wives tail....
