Not a very good story because its not really accurate. I thought the 6.8 was chosen to defeat body armor without the bulk and weight of 7.62x51. I have an opinion of the new ammunition choice and that opinion is negative.
I thought all weapons were being chambered in .277 Fury (Sig) but it appears only the M250 SAW and designated marksmen will shoot this. Our government can spend Our money like nobody's business.
