First of all I freely admit I know almost nothing about reloading or the physics involved with ammo pressures.
That being said I'd like to know with modern technology and materials why we don't see ammunition the size of the 5.7x28mm yet still capable of pushing a 40 grain bullet to well over 3000fps.
I'm surprised they haven't moved beyond brass for high end military weapons. I bet spec ops would love a gun that had ammo as compact as the 5.7 yet had the same or more energy then 5.56.
Maybe some titanium shells loaded with some kind of higher powered propellant fired from iconel chambers/barrels.
Maybe it's just a cost issue, but it seems odd that I've never seen any mention of moving away from what amounts to over 100 year old materials and technology.
