Did you anneal the cases ?if you resize the brass case by only bumping the shoulder back .002 - .003 you will greatly increase case life . these cases were loaded close to 20 times , 18 I think . the brass I'm using now is about used up , some of it's on cycle 15 . you should get the tools to be able to measure case length , and learn to set up your dies . from my experience the brass all seems to fail at about the same number of fires . meaning , your brass is probably about all used up , being it was all sized the same way .
I've removed a few separated cases , by using a large cleaning brush . pull the bolt , jam the big brush into the remaining case , and pull it back out . clean the chamber and get shootin .

you can see the different stages of the cases . some have a smoke ring at the fracture . some show a lighter ring where the fracture will happen . some look normal .

some separated cases with a tool I made to feel inside the case . I've never felt a sharp edge inside where they fracture . I'll feel a dip , a rounded out , or hollowed out , area where the brass is thinning at the place they separate .

have used this method on my Ruger #1 swiftThe problem is almost always caused by repeatedly oversizing as stated above by others. My buddy has this problem fairly often with one of his Weatherby rifles.
Just use a brass brush that is larger in diameter then the case body and use your cleaning rod to push it into the case until it stops. Then pull the brass brush out. It should have the brass case stuck on the brush. I've seen this done many times.
Like this. I have struggled to extract one separated 6mm Rem case with a .38 bronze brush. Learn something new every day.I tried to get a stuck case out with a tight brush,patch and couldn't get the **** thing out.Finally I packed a patch inside the broken case from the chamber side.Then I put some JB Weld Kwik on a a small swab and carefully shove it inside the broken case.I waited about 30min for the JB Weld to set.Then I inserted a cleaning rod from the muzzle end and let it drop about six inches or so to the stuck case.On the second drop the case popped right out.View attachment 305775View attachment 305777
Ito a Seekins Precision Pro Hunter.Did I miss what kind of rifle this is? I agree that oversizing the cases caused the separation, but I think RD57 hit the nail on that head saying what happened to him. I think that you have a long chamber, and need to measure a fired and sized case side by side to see how much you're moving the shoulder on the case.
