stronger bolt material for high pressure loads??

I think if you consider what you would loose in brass life and barrel life by adding 15k to the Grendel you will end up in the red vs using a different cartridge that said there is already a bolt set up to handle that kind of performance it's called an ar-10 if you need it to be a Grendel you could chamber the ar10 in Grendel and push it as hard as you want and you will still fall short of a 260 the Grendel just does not have the case capacity to push much more and even if you do push from 2500 to 2700 if you run the balistics all it does is buy you an extra hundred yards from 1100 to 1200 when you consider that a 260 can push the same bullet to 3000fps but you get a heavier package and burn 50% more powder.... There is no such thing as a free lunch
