My 6920 doesn't like it. Found Tula on sale at Cabelos a while back for $4.50 for a 20 round box. Bought several hundred rounds for range shooting. Every couple of magazines, the spent shell casing would become stuck in the chamber. Most of the time I could just bump it out (gently bump the butt stock on the bench while pulling down on the charging handle). Last time out, the extractor nipped off the rim of the shell. Had to take it home and tap out the shell with a cleaning rod. No more steel, brass only now. Guess you get what you pay for.

There was a similiar thread on the general AR discussion group a few days ago, I made the mistake of making a comment. The flames started with, "mine eats them for breakfast", "you don't know how to clean a rifle", etc, etc. Well, I'm very careful about cleaning my rifle and oiling after every trip to the range. Switched to PMC, 55gr, FMJ brass cased rounds. Have shot a couple of thousand rounds without any problem. Is this scenario fairly common?

I hadn't thought about that. When cleaning the bore, I put oil on the last patch then rub it in the chamber. Should be running the chamber dry?

how much do you think you got in there? a lot? a very light coat?
too much will cause high chamber pressure and a stuck case

Quote from Ken Elmore, owner of S.A.W., when I attended  a Colt Armorer's school he taught : "Wolf ammo is the Russians revenge for us winning the Cold War". He said that steel cased ammo is not good for AR's, especially the laquer coated cases. Ken also said why risk causing problems in your $1200 rifle to save a few bucks on ammo.

I only use American made, factory loaded ammo (I will shoot my own reloads if I ever start reloading).

YMMV

I keep a couple of short cases of Wolf on-hand for function testing, primarily in new builds. By my reckoning, if an AR will shoot Wolf reliably it will shoot damn near anything.

I have not had any issues with the 6920.
I have shot thousands of rounds (9mm and .223/5.56 but mostly 9mm) of Wolf and have not had a problem.  If you are buying ammo, using it for plinking and do not reload, i believe it is fine to use.  If we were to go to AIM at this moment and buy 20000 rounds of WOLF and 20000 rounds of PRIVI (the cheapest brass cased) the Wolf would cost you $4,300, the Privi would cost you $8,250...This is of course, as I mentioned, you do not reload.
With that much in savings you could buy another rifle and 10000 more rounds of steel case Wolf  
With all of this said, I do prefer brass, not only to reload but beileve it to be easier on the rifle.

in addition to the lacquer issues mentioned above, the steel on steel will cause excessive wear to the extractor.  my foray into combloc 5.56 had me replacing gas tubes and extractors at around 2k.
