Having worked behind a gun shop counter... My 2 Cents...
Wolf is cheap. That can be a good thing.
My main concern was always, if Wolf (or Chinese ammo for that matter), blows up your gun, who do you growl at? Will they even care?
Having seen a few very nice firearms beaten up by bad ammo, I always put it this way to my customers.
"If you have a nice, new Ferrari...do you put 85 octane in the tank?"
