Grendel as a Universal Infantry Cartridge

[Trooper]

Just remember that the 6.5x55 Swede showed that it does not take a fast bullet to get results. Thus a 140 gn bullet in 6.5mm was doing, at 2500 fps, as well as heavier rounds in either 7mm or 7.62mm (.30 caliber).

And we want a GPC that is not only an infantryman's cartridge but also a designated marksman's. And can be used in general purpose MG patterned after a SAW.

As for the 7.62x51, outside of the M240 and the DMR, it has fallen out of favor. Either the .300 WM Mk 248 or the .338 LM (or .338 NM) have become the sniper rounds. And the .338 NM could be used in a version of the M240 (or General Dynamics version) MG.

What the 6.5mm and the .338 have in common is that both have out of the box good BC.
