New Army "Caliber Configuration Study"

...why Bill Alexander hasn't really gotten into all this, hasn't developed military loadings, hasn't developed a 65G LMG...

So, yes, if they decide they want to match 7.62x54R ball with an intermediate lead-free projectile, it's a simple matter of bullet design and case capacity. Then we'll see if the result is acceptable in all the other pertinent parameters.

I find it quite understandable that Alexander hasn't developed a Grendel LMG. There's just too little chance for AA to make a profit from such a venture.

It's just that, after a decade of endlessly discussing nothing but theory, I'd really like to see some testing done to show how performance of a 65G LMG compares to the PKM (and other machine guns) in reality. Or, if not a 65G belt-fed, at least an M27-type automatic rifle.
