Grendel as a Universal Infantry Cartridge

[woohoo]

Add to that that well over 92% of soldiers and Marines would not be capable of exploiting the added capabilities without significant changes to the training programs, and the fact that most marksmanship instructors are pretty clueless about wind drift, let alone trajectory.

On the other hand, everything is already in-place if a Grendel-like cartridge was introduced for belt-fed machinegun training. The gun and ammo would just be lighter, with less recoil, and less wind drift.

So after 5 years of saying they should adopt the Grendel to replace the M4 are you now saying they shouldn't but they should use it in a MG?
