Yup I sure did hate it when it happened! I must confess to how stupid I was during the whole process of removal. Instead of researching solutions on stuck case removal I blindly jumped into action.
First mistake was cutting off the mangled rim with a hacksaw. Second was drilling out the web so I could insert a screwdriver up into the case. I figured I could simply jam a screwdriver or EZout in there and the case would twist right out. WRONG!!!
Now in my infinite wisdom I drill the case out even more thinking I'll get it thin enough to split and pry out of the die. Again this was WRONG!!!
Finally I learn you're supposed to drill & tap the case web and pull it out with a bolt. Lucky me I had just enough case wall material left to tap with a 3/8"x24 tap and engage a bolt to pull the case out.
There is no damage to the interior of my die however I do need a new decapping rod and expander ball. I robbed one out of the 222 die set so I can continue sizing a bucket full of 223 brass.
I'm done confessing my ignorance and will never again snicker when I hear of someone sticking a case in their die - I've been humbled!
