How clean is the chamber? A dirty firearm is prone to steel cases getting stuck

Fired lots of steel case in the last year.
Rifles: LMT, LWRC, Delton.
Not a single problem.

Some Ar's are more prone to problems with steel case than others tho ..
Also: Which bran do ammo was it? TulA?, Wolf military classic? wolf WPA? brown bear?

What exact model of AR?

Probably just a fluke. Put more of that steel in and let her rip

Steel cased FMJ
Walmart $5.27

I took it home and knocked the case out with a cleaning kit and fired another 79 rounds of steel case through with no problems.

Here's the extractor, looks fine to me just dirty.
Just some thoughts:

Carbine gas systems tend to be a bit over-gassed. This is because of the gas port being closer to the chamber and also having more bore past the gas port before getting to the muzzle. So gas pressure at the port is higher due to the lower bore volume to drop the gas pressure before venting gas rearward into the bolt carrier. Gas is also vented rearward longer, because the bullet has farther to travel past the gas port before exiting the muzzle. This blows more garbage into the bolt carrier and action than you would get from a midlength or rifle length gas system. The higher pressure makes extraction a bit harsher than the other gas systems as well. Using a heavier buffer can make the extraction less harsh. Steel case rims are a bit more brittle and can shear more easily if a case is stuck and jerked more harshly.

The AR with its direct impingement gas system and steel cased ammo can make a dirty chamber faster than average, because the steel cases don't expand as fully and gas and carbon blow around the cases and dirty the chamber up faster. If the chamber was never cleaned of the factory oil with solvent and a chamber mop, that powder residue and factory storage oil could cool and make a gritty paste that would potentially make a prime place for a case to get stuck. Also if you cleaned it and stored it with excessive chamber oil and didn't swab it out before shooting it could I tease some hydraulic pressure around the case and make it harder to extract.

It doesn't seem to be an extractor problem, because it held on tight enough to rip off the rim.

None of what I shared may make you want to continue to use steel cased ammo. Just some things to consider for folks who do use steel case in ARs.

Its not just a fluke I had the same thing happen on 2 different ar and they wouldn't reliably shoot out of an m1a.

Well I sucked it up and used the rest of my steel, about 120 rounds total just that one FTE so I'm gonna write it off as a fluke.

It just gave me a bad impression since it was the first steel case I used in it.

I see this happen alot in non chrome lined chambers, never seen it happen in a quality chrome lined chambered barrel . Never stuck one in a 5.56 AR . But have in a 7.62x39 non chrome lined barrel , a little bit of polishing to the chamber and its been fixed
