Ideas on a really stuck case

I was recently given a box of reloading stuff to sort through from a late uncle.

Inside is a small base .308 Win sizer die with a stuck case. Either he didn't know to drill and tap it to remove it or the case head seperated from the pulling because, as you can see from the pic, now it's really stuck.

Any ideas on how to get this one out?

I was thinking about hammering in an easy out and hoping the twisting would get it to break free. A little hearder to get out something with an easy out when it isn't threaded though lol.
 
Send it to the Manufacturer and they will take it out and if it is damaged or worn out, they might even give you a fresh one. Worn dies do stick cases more, so it may be already a bad die.
 
Here is a quick easy way that has worked when I did this for a friend in the past.

Find a screw or tap that will thread into it fairly easily. Not enough to spread the case into the walls, but enough to have some bite.
Now heat the die without the screw/tap in it in the toaster oven. I used 350'F and it seemed fine. Get die nice and hot.
Have a can of AeroDuster or other similar product handy. When discharged upside down, the liquid comes out at about -45'C
Take HOT die out of oven with heavy leather gloves. Spray liquid from AeroDuster can into shell casing only. This will freeze it and shrink it. If it does not fall out then thread in screw/tap and pull out brass.
This method works due to expansion and contraction. The steel expands from the heat, the brass case shrinks from the extreme cold and a clearance is obtained.
This is similar to the method we use here in the shop to install new bronze guides into aluminum cylinder heads however we use liquid nitrogen. Allows for a nice tight fit when the parts all reach the same temperature.

I would think that hammering an easy out would make the case even harder to get out because you would be expanding the case even more.

You're on to something with the Aeroduster there.
But you can also get aerosol freeze spray in a can, and I have used this heat/freeze process for seized bolts.

Block the neck of the case with cotton batton or similar. Carefully pour or syringe some epoxy, JB Weld or similar into the case. Allow epoxy to cure. Drill and tap epoxy and pull with stuck case remover or drift out from the other end if there is room for a small drift through the top of the die.
 
Porschemann's method will work great. Try this for your cooling spray. Great stuff and a handy fire extinguisher for your gun room or home at the same time.

I own an auto repair shop, we constantly heat stuff to free up seized bolts etc. This stuff works wonders to quickly cool something, and we have put out a few small fires with it over the years as well.

I have done something like this before. Low tech.

use a brush and some de-greaser inside the case, first, so the epoxy will hold.
