Default Ammo: FTE

Shot my rifle for the first time today. Bought Tulammo in 55 and 62 grain .223, and had a few problems. Every so often, the extractor would take a chunk out of the spent case rim, but couldn't extract it. Then a fresh round tries to feed in behind the spent case. Frustrating to say the least.
I've seen some posts about similar problems with The steel cased ammo. Anyone have any insight about this Tulammo? Is it a mechanical failure, or something related to the cheap ammo?

non-chromed chambers and steel cased ammo dont mix. if you let a steel lacquered case sit in a nonchromed hot chamber the lacquer will melt and stick to the steel of the chamber as well as the steel case. lacquer will not stick to chrome.

thats why some ar15 run steel just fine and others dont

to clean lacquer out of your chamber use a chamber mop and denatured alcohol. denatured alcohol disolves lacquer instantly.

pistol rounds have a hard time generating enough heat to melt lacquer. not all steel cases use lacquer as a coating.

Is all steel ammo lacquered? Compared to Monarch, the Tul was not shiny cases and red primers.

not all, some steel uses a different coating. you can tell if its lacquered by using a bit of denatured alcohol and if turns sticky its lacquered.

if its copper washed or brass it definately doesnt have lacquer.

you can wipe down each round to get the lacquer off if you want to go through the trouble but then your exposing the steel case to the elements and rust will set in.

What barrel/chamber? Who put it together, did they check to see if the chamber was in spec?

If my barrel and chamber are chrome-lined, what other possibility is there? Does the steel expand to the point that it might not eject? Or maybe an extractor problem with the bolt?
I believe my chamber is chromed. It an SAA barrel. Description says it is. Emailing SAA about the problem.
