I agree with those who say that the biased ones are the old timers who jump to the conclusion that Wolf is worthless ammo. I've shot many thousands of rounds or Wolf, so I know that the bias lies with the old salts, not the propoents of Wolf.
Another thing about Wolf: The ammo is made in four different countries that I know of, and not all are Eastbloc. Steelcase at Tula in Russia, the target shotshells in Spain, buckshot and slugs by Lapua in Germany (I dare someone to tell me that Lapua is crap), 22LR in Germany, and the new brass Gold line at that unpronouncable place in Yugoslavia.
I'm not saying Wolf is as good as the cheap American stuff, but it nearly is. Chrono readings seem to average about 1-3% slower than American ammo. About one in a thousand rounds needs two shots to the primer to set it off (I'm guessing an occasional high primer). And it seems to be dirty, so after two days and 500 rounds in the desert, my Mini will not always cycle--the bolt carrier sorta gets stuck due to all that carbon, dirt, and lack of lubrication. But 99.9% of the time it runs just fine.
And I hate to be a spelling tight-ass, but I see this over and over again--there's only one "f" in Wolf.
Silver Bear, though, is a different story. I have 1000 rounds from one lot of 45, and it is loaded with astounding inconsistency. One shot feels like a +P, and the next is so wimpy it won't even cycle. The .223 seemed fine, though innacurate, but I haven't shot that much of it.
