Let me go on record as being a fan,also.
The US Military does NOT need a short range light caliber bullet in today's conflicts. They need something with more weight that is a boatail spire tip design that is heavy enough to buck winds when shooting across canyons.
I would have MUCH preferred a 7mm round in a FN-FAL,but nobody asked me.
Soo,what will happen is the Defense Dept will spend tens of millions of dollars re-inventing a "wheel" that will NOT outperform the 7MM FN-FAL that can already be bought off the shelf from FN,and not accomplishing anything at all other than fluffing up some "connected" bank accounts.
Hell,chances are it won't even be as good as FN-FAL because they are going to HAVE to make some new modifications to a proven design to justify all the tens of millions they spent to get there.
