Ar-15 experts step in please..

Did the bolt lock back? If not, the gun is too dry and you need to lube it properly. If it does lock back, I'd say you have an extractor problem.

Are you running Wolf? If so, you probably need to break the gun in a little more because Wolf is a little wimpy and steel cases cause a few issues (I'm not a snob, I use wolf for blasting purposes).

All of this said, most of the issues I see at the range with ARs are lack of lubrication.

Get an extra power spring for your extractor and run it wet with brass case ammo.

most, if not all, 223/556 barrels are now chambered 223 wylde and are safe to run any factory ammo, super hot reloads might be a different story tho. some folks might load up to kaboom zones

i've had a couple of bolts that had two o rings, that's exactly 1 too many

What's the ejection pattern for the rounds that do successfully eject? IIRC, should be to your 3 o'clock to 4:30 position.

Could be a weak extractor spring.

It's the extractor. Change to a heavy spring and oring. Stay away from steel case ammo

Cheap ammo, and folks expect stellar results?
Never, ever try to solve gun issues with cheap ammo.
Verify with premium stuff.

I tell folks steel ammo in 223 is save now pay later. Pulled extractors, stuck cases and scratched chambers from trying to knock stuck cases out. Not worth it.

 

[dennishoddy]

I’ve never shot any steel cases from any gun I own.
Reading reports on OSA in the past made me think, hmmmm

i only shoot brass cased as well, i have some rooshun x39 that has a brass case, but it's a bi-metal bullet so haven't fired any of that yet, last resort ammo
