Heck of a good price, but, the only Wolf ammo I own is their military ammo that is lacquer sealed.The red band you see around the primer and where the bullet meets the case. That makes it weatherproof and good for storage.
People who say it's hard on extractors are probably right. If that is the problem for them then they need to buy a better weapon. (price wise) My Kimber runs it without any problems where other 'brand names' jam.
Edit: It's bad because it's Russian, remember that.
