Re: wolf primers
They're good. One thing the Russian's have always done very well, is primers. They produce some of the most accurate 22 rimfire ammo in the world, bar none, and a lot of their success comes from the priming mix they use. When Federal created their Gold Medal Match stuff some years back, they tried very hard to duplicate the Russian priming compound and production methods, including the dimple on the case head. They got close, but the original russian ammo was incredibly tough stuff to match, much less beat. Same sort of expertise carried over into their centerfire primer production.
If it makes you feel any better, I just picked up 30K of them from Grafs yesterday, to be used in my Service Rifles for NM competition.
