I have taken a lot of stuck cases out of dies.
If I am given the stuck case before anyone has done anything with it, I can usually remove the case, without using the drill, tap and turn method. Thus, the dies and case will have nothing done to them, permitting the case to be resized and used again.
I was once at a gunsmith's shop when he got in a freshly stuck case, to be removed. The gunsmith was quite busy, so I volunteered to take the dies home and remove the stuck case, which I did.
No drilling or tapping and full use of the case after. And no marks on the dies.
