From the IAA forum:
"The .264 USA is one of the intermediate cartridges that will be tested in the current lightweight ammunition program, which also includes 7.62x51, 5.56x45 and a new .277, all using polymer cases. The proposed shooting plataform for those two new calibers is a AR-10 type rifle."
