I don't think anyone cares about the .450 Bushmaster, it answers a question nobody was asking, and aside from the novelty of being different it won't be around for long. The AR is trying to be too much to everyone 5.56/7.62/6.8SPC/6.5Grendel/.450Bushmaster/.458Socom/.410/9mm/.50Cal ect. ect. ect. Problem is IMO that the system itself isn't the pinnacle of reliability or simplicity and is dated. The only usefull cartridge I see extending it's usefulness is the 6.5 Grendel along with piston driven alternatives, but then why not simply move to a more updated system and be done with it.
Having large calibre makes sense IF AR are allowed to be used outside of the fire range, at the end of the day what ever flying out of the barrel of an AR will only end up making holes in a piece of paper or go "ping: on stationary plate of steel, the only satisfaction you will get out of it is that you just spent more money doing it than the guy next to you
