what are they going to do when that almost all hunting rounds will blow through it too?
They are going to have a hissy fit, and I am going to watch and enjoy it.
Since Heller, ammunition is as protected as firearms. The government must have an overriding interest (lots of police killed by M855) and the legal solution must be narrowly tailored. None of what's on the table meets either condition.
They could make a case for a specific type of ammunition if they could show that it poses a special hazard to society. So the ban on tungsten core armor piercing ammunition is probably constitutional and proper.
But M855 poses no special hazard and cannot be singled out. Neither can they ban all rifle ammunition. The SCOTUS justices would roll their eyes, say "not this $hit again" and strike down the ban.
If M855 is like all other rifle ammunition in common use, the game may go on for a while but the winner is already decided.
