Bought a thousand round box of Wolf to try in our DPMS ARs. DPMS recommends no lacquer coating but says nothing about the newer polymer coating process. A good source on the internet says that "all ammo produced by Wolf is now polymer coated which solves the problems of the coating melting and sticking to the chamber/bore". The gunsmith at Gander Mtn does not recommend "cheap foreign-made" ammo, but in the same breath said that polymer coating will work ok for me. He recommends a very good cleaning after using cheap ammo. Anyone use Wolf in their DPMS AR.
