It's in a steel housing, as stated.  I'm fully prepared to accept that 
the high temperature and pressure generated by the gunpowder may not set 
off the high explosive.

I'm not prepared to accept that it will do 'nothing' as you said.   I 
hoped against hope that you might have some special knowledge in this 
area.  I should have known better.
