   That new Federal steel case is designed for 80,000 PSI as the standard   
   load. The material is suppose to be able to expand slightly to help   
   keep the case locked in the chamber and not blow back against the bolt   
   as hard. Can be reloaded too but didn't see any detail on that yet. Not   
   that I went looking for it either.   
      
   Speculation was that it will be used to boost older rounds pressure too   
   for newer guns that could probably handle the higher pressure...
