If it only happened with reload, then it looks like your reload just needs a little more crimp, or maybe just a tad shorter.
Next time it does that, pull the slide back, take out the shell and look for the shinny spot on the shell. It could be the mouth of the case or the bullet touching the rifling.
I ran across a guy at the club that had the same problem (except a lot of them) with his Gold Cup . After talking to him , he said that he does not remove the flare, because he does not want to rework the brass so it lasts longer !!!!!!!!
Did the extractor catch the rim of the case?
When you pull the slide back, is the round still in the chamber?
That looks exactly like what my gun would look like when it suffered an inertial feed.
The round popped out of the magazine early and the rim was ahead of the extractor claw.
If this is the problem you are having, you can mitigate it in a couple ways.
1. Make sure magazines are clean and have no oil in them.
2. Use a GI magazine with a dimple follower.
3. Make sure your magazines springs are not worn out.
4. Make sure your extractor is fit, polished, and beveled correctly.
5. Make sure there is at least 30 .oz of tension on it.
Gun is new, these are the first hundred rounds. Springs are all factory.
Was not able to check for markings on the cartridge as I never had to eject any of the rounds. They were all like that, all were under the extractor as they should be. A light tap put them all fully into battery and they fired fine.
Ejection was pretty weak but consistent, the brass was in a small pile on the table in the bay I was in.
