Note flame directed at shoulder as Paul suggests above.
Cases that have been overheated can sometimes be salvaged by running them through a conventional sizer/expander die several times. If the grain structure wasn't totallly wrecked, this can work-harden the neck and restore the elasticity needed for adequate neck tension.
Are you holding the case with your fingers?
