I'm getting set to graduate from loading 40 to loading .223, and upon inspecting my brass I found quite a bit of these, where the neck is wrinkled. Will a FL sizing die straighten these out?

Interesting mark, but hard to see exactly what it is. They will probably be fine. Size a couple and see what they do.
 
Externally, the sizer will flatten the wrinkles out to a certain extent while the ball expander will then come through and do the same from the inside. You will be left with an image of the distortion when you are done.

Lube the cases well.

I darn sure don't know what caused this. Are they YOUR fired rounds and if so were they factory ammo?

It's almost as if the bullet was pushed in on the case mouth collapsing the neck before it was straightened and entered properly. Almost....but there's no distortion around the case mouth. Hmmmmmmmmmm
 
Looks like the neck is snagging add it is being chambered or ejected. is like to know more of the story.

It'll probably reloaded but I'd expect it to fail faster if it keeps doing that.
 
i FL should take care of that issue.

Question would be, is this brass from your gun or did you buy in brass. if it is bought in or range pickup brass, FL size it. If it is brass fired in your gun, you may want to have the gun checked at a gun smith.

the brass with wrinkles will become weaker sooner than straight brass. just keep that in mind.
 
Along with the neck showing those odd wrinkles, it also appears that the case body may have been experiencing a similar effect prior to being fired, at least from what I can see in the picture? My guess is the brass was improperly crimped which buckled and collapsed the brass in multiple locations, prior to being partially ironed out when discharged.
I would do a FL sizing, and then very carefully inspect them before moving onto reloading them again. Bad things can happen to brass when it gets severely deformed like those have been. Proceed with caution, is my recommendation, in my opinion.

It's think the shoulder would have caved in if it was from crimping. I first thought bullet seating but the case mouth isn't damaged.
 
I'd bet dollars to doughnuts those are cases from pulled down military rounds. Those are exactly the kind of deformations some industrial bullet pullers can make.

I think we have a wiener!!

Nothing like that came out of a gun after being fired I betcha!
(Unless the whole chamber was full of packing grease or something)

I would try resizing them and see what they look like then.

Any with remaining wrinkles in the shoulder should be discarded for safety reasons.

Actually they did come out of a gun that fired it. The problem is I no longer know whose. It could have been my son's AK or it could have been a strangers. I'm pretty certain I didn't own an AR yet when I picked this brass up, but I could be wrong.

I decided to go ahead and size it while I was doing some other cases, and it seemed to iron out the wrinkle just fine.

If you have a buddy with a bore scope you need to go in for a looksee. It could be rust build up in the neck.

Had a buddy come about a couple months ago who said he head hard bolt opening. I checked with headspace gage and bolt would not shut on GO GAGE.

I pulled out bore scope and the chamber was full of rust. He had gone deer hunting in the rain and came in and put rifle in rack with round in chamber.

He was very lucky. I cut off two threads and set barrel back and cleaned up 95% of the problem. He says it now shoots great and no problem extracting.

A new barrel would have run him 400.00 or so.
