Most crimped LC brass isn't too bad to deprime but I have had a few that were very stubborn. I have even had a few that the decapper punched a hole right through.
Usually if they give more than normal resistance I pull them back out to make sure they aren't Berdan primers. It is easy to miss an odd case then bend your decapper.
A punch will do the trick with the above stated socket underneath the case.
The Lee hammer kit is about the same as the Lee decapping die as far as strength goes. They work well but a good steel punch should have them both beat.
