First, lacquer hasn't been used on Wolf and Tula ammo for several years. It's a high temp polymer that's currently used. It doesn't collect in your chamber and neither did the lacquer used before it. If you take an old lacquer covered steel case and hit it with a propane torch and get it glowing hot, you still can't wipe the lacquer off -- and that's FAR hotter than it gets in the chamber of your rifle.don't shoot steel ammo. really. it depends on your setup, but some guns just don't like it, particularly carbines, as they tend to run 'hot' physically. the shorter barrel and gas system loves to collect the steel case lacquer and it builds up on the bore, causing your FTE.
I don't own any firearms in .223, all of my rifles are 5.56mm rifles. I never have any issues with Wolf in those rifles and shoot it literally every week.So if these types of issues are usually due to carbon buildup, will they be more prevalent when shooting steel .223 out of a 5.56 than when shooting steel .223 out of a .223?
