You may or may not have an issue after you get the case out and that is....
The die isn't carbide lined like a pistol die so it may be scratched inside from the siezed case against the die wall. You'll know right away on the next sizing because the sized case will have lateral scratches in it. If it does (case scratches), it means the inside of the die has inclusions that need to be removed and can be with an appropriately sized buffing bob on a mandrel chucked in your cordless drill and a bit of fine lapping compound or good old rubbing compound.
The buffing bobs and the mandrel are available at any hobby shop or Lowes that sells Dremel accessories or on line at Amazon.com. Size on to fit snugly, a dab of compound and tun the bob inside the die body, keeping it moving in a cross hatch pattern. Don't linger inside the die or hold the bob in one place, keep it moving and it won't take long do check the die every 15 seconds or so of buffing.
Remove it regularly and check the inside of the die with a borescope (if you have one) or size a cartridge and check to see if the scratches are gone. Just don't forget to clean the die inside before sizing the brass to remove the compound. I use brake cleaner in a spray can for that. After you clean it, lube the inside of the die with case lube and make sure the vent hole is open so you don't deforn the bottleneck.
