Take a look at the necks on this used brass. What would cause this kind of distortion?

Contact with the breech on ejection. I have heard it called "positive ejection" by some and is usually not considered a bad sign.

Is that by any chance a Ruger?

Sorry, don't know what kind of rifle it came out of. This is from a purchase of used brass.

What is the headstamp on the brass. Looks like they are 7.62X39 Russian. If so, I think they were fired in Russian made Saiga or Vepr 7.62X39. I have seen brass necks like that coming from Russian Saiga semiauto rifle.

Hey Steve, Since Davaa has seen it come from rifles that way, I do believe my "guess" below is probably full of beans.

It looks like someone Partial Neck Sized the Cases and fired a Low Pressure load in them to me.

But, I'd go with Davaa's input. Cases #2 and #5 have the tell-tale bent Case Mouth that often occurs with semi-autos and full autos as they hit the Receiver on the way out.

My son produced some cases that looked like this when he fired .375HH rounds in my 425 Express. What results is a double shoulder, the first tier at the top is the portion of the case that was in the barrel, the second tier was the normal case neck, and then the shoulder and case.

I suspect that someone fired a cartridge that uses the 7.62x39 as "parent" case but uses a smaller diameter bullet, say 243, 6.5 or 270. Or, fired a standard 7.62x39 in a wildcat that uses a slightly larger bullet and shorter neck, say an 8mm. In either instance, it chambers and fires without incident, but leaves you will some funny looking cases.

By-the-by, my son hit his target at 25 yards with the 375 bullets launched from the 425! Kudude

If the cases came deprimed, someone probably ran them into the die only far enough to pop out the primer and only sized that much of the neck.

The primer is still in place.
