The problem was never with the laquer, it was with that red sealant all over the primer, and case mouth that melted and jammed rifles, the polymer coating doesn't make much of a difference from the military classic(still laquered, but no globs of red crap). The problem in an AR is differences in steel cased and brass cased ammo. Steel cased ammo doesn't spring back the same as brass, making it harder to extract in tight chambers, this is part of the reason 7.62X39 (designed as steel cased) has the large taper angle. try to chamber a fired brass case, and a fired steel case, the steel case normally won't chamber, the brass will, this puts a strain on the AR extractor. Berdan primers used in most steel ammo is quite a bit harder than boxer primers, and wolf has about the hardest there is, this is to prevent slam fires, but puts stress on the pin. look at a fired wolf vs most any brass to see the dent in the primer. wolf tends to be fairly dirty, but it is not corrosive, and will just wear out the extractor and firing pin quicker, both are fairly inexpensive and easy to replace if you do choose to shoot wolf. I have found it to be quite inaccurate in my AR, and am not the type to enjoy more than the occasional bump firing blasting. For accurate target work, or even quick aimed fire this is not the best stuff.
