As far as durability goes, lacquer coated ammo is the best; it will last far, far longer than silver bear. IIRC someone did a test at some point where they left golden bear, silver bear, polymer wolf and lacquer brown bear exposed to the elements. The polymer and silver bear both visibly rusted, the golden bear rusted a little, and the lacquer stuff was totally unaffected.
Golden Tiger is probably about as durable as the AK you're shooting it from with sealer on both ends and a lacquer case. It's the only stuff I buy for FMJ ammo. Of course, none of this matters if you're just gonna take it straight out of the box and shoot it from a bench at the range.
