   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...

   If it erodes rifling faster it may not become popular, as with the .264 Win   
   Mag. Battleship gun bores eroded enough that the ballistic computer   
   computation included compensation for the number of rounds fired, and the   
   rifling was in replaceable liners. "All Quiet on the Western Front" states   
   that German artillery barrels were so worn towards the end that the slowest   
   shells would fall short into the German lines. I've read that double base   
   powder burns hotter and causes faster wear than single base.
