I bought some range picked up .223 brass.

When I try to run it through the expander die the case smashes bown causing buldge in the case just below2 the cone.

I have adjusted the die twice with no change.

I tried using bullet grease and it seemed to help a little.

Most of the cases I have so far a smashing.

Any iddeas what may be causing this.

It sure would be nice if you would post a picture of the problem you are having. I am having a hard time visualizing what is going on.

Have you trimmed the brass? Is the expander you are talking about inside the sizing die or a different entity?

Measure a few pieces. Maybe it's already too long and the mouth of the neck is hitting the inside top of the die and crushing it just below the shoulder.

More information.

These are range cases.
They were cleaned before I decapped and sized the case.
The process I am having trouble with is expanding the next to accept the bullet.
I use lube to size the case and tried lube to expand the neck.

Just below the angled part of the case, the case will buckle or smash down. Leaving a bulge all around the case.

I have a new smart phone and don't know how to take a picture and sent it yet, if ever.

My suggestion to you is to take whatever "tool" you are using to try to expand the neck of the .223 brass to the nearest trashcan and drop it in. There is absolutely NO reason to bell the mouth on a piece of .223 brass.

Then go back to the press and screw in the bullet seating die, set the bullet on top of the sized piece of brass, push down on the handle and seat the bullet in your prepped brass.

Here is a video of a guy at RCBS showing how to set up a bullet seating/crimp die. To see how he sets the bullet on the case, go to the 3:00 mark and it shows him setting the bullet on the piece of brass. The brass is not belled (expanded). Tghis is not .223 but same principle.

I may be over simplifying this. If so please forgive me.
when resizing the brass should be clean and lubed. I know "they" say carbide dies don't require lube. Don't believe it. Your arm will thank me later. That said, too much lube can build up in the resizing die causing exactly what you are describing.
223 require little to no belling of the case mouth. So back that center screw on the die out until the problem stops.
what brand of dies are you using? That might help us walk you through proper setup.
a common mistake in new reloaders is to over flare the case mouth until it looks like a blunderbuss. Even with cast bullets you only need a barely visible flare.

I am really, really, really curious what you are using to try and expand the case neck. As others have stated, you don't expand the neck to accept a bullet in a .223 case.

All of this.
YOU DON'T BELL THE MOUTHS OF RIFLE BRASS.

I can see the shoulder being smashed and even though it is blurry, I seem to see the mouth belled, the question is what are you using to cause that.

Now take a picture, blurry or not, of the tool you are using to expand the mouth, which is what is causing the shoulder to mushroom.

By the way, the stuff in the background is clear, back your camera up just a hair and it should be clear.

The process I am having trouble with is expanding the next to accept the bullet..
Let me try to explain this very slow You - do - not - have - to - expand - the - mouth - on - rifle - brass!

I do not reload. I enjoy very much reading about it. I learn so very much about a whole lot of topics.
And, in a lot of cases, like this one, get one heck of a lot of entertainment too!
