Grendel LMG

[stanc]

I wouldn't want downrange LMG performance in close-range carbines anyway...makes for disastrous results in the house/CQB, and increases recoil over the current systems unacceptably.

IIRC, we've been over this point before. Advocating two different loads -- heavy ball for machine guns and light ball for carbines -- is a nice theory, but the reality is that nearly all the world's armies (China being a notable exception with the 5.8x42) use only one loading for carbines and LMGs.

IMO, any proposal for the use of two loads is a non-starter.
