you'll lose it before you wear it out. and if you do overlook a small crack near the mouth it's not a big deal. it will split down all the way very noticeably when you fire it, then you can throw it away.
It's not a real healthy thing to do to your chamber, but having it happen occasionally is not a big deal.

Just shoot them until they complain (have a big split) or the primers fall out.
