Not one thing to do with shotguns but trust at least some of my buddies here won't LOL! Was sizing some .270s with a lee hand press and for wharever reason thought it was time to clean the sizing die of any accumulated case lube. Sprayed with wd40 and ran a cloth up in the die to clean. Picked up a brass that hadn't been lubed and you guessed by now I have a stuck case. 30 minutes in the freezer didn't help nor all the muscle I could put on it. When you get through laughing help me brothers!
