I have a 14" .223. It works fine with brass cases whether new or re-loaded. But if I use the cheap ammo with laquered steel cases, they get stuck. It seems like the laquer is melting and glueing them in. I havent had this problem with any other firearms with Wolf ammo. Any thoughts here? I was thinking of trading this barrel, but have put it on hold. I dont want to trade bad goods. I could use some help here as to why this is happening........Robert
