Grendel LMG

[stanc]

Stan & Tony,

Seriously, think about the detrimental effects of a cartridge/projectile/weapon that can deliver substantial downrange energy at 700m, and what it would do when I enter and clear a room, hallway, alley, or courtyard as a member of a combined arms team, with adjacent units within proximity led by officers who are doing multiple breech points for the first time in combat because they never trained on it.

I can only note that in WWII, house clearing was done with weapons firing .30 Ball and AP ammo, so perhaps it's more of a theoretical concern than a real problem?

Think about the recoil a 130-140gr class projectile will present for a carbine being fired on SEMI, especially in rapid succession.

IIRC, you have a 6.5 Grendel carbine, and one in 5.56 NATO. Have you run any tests to determine if there is a significant difference in that regard?

I don't see a compromise between the requirements for carbines and LMG's to use the same projectile. The SAW in 5.56 is on the wimpy end, so if we are wanting to get rid of the beast M240 in 7.62 for dismounts, it has to launch significant weight projectiles that will pattern well with enough energy out to 800m for human targets, and penetrate light-skinned vehicles at 500m, while blowing through most walls within 100m. That is way too tall an order for a light-recoiling carbine, but perfect for an LMG and DMR.

Perhaps it is, but how likely is it the US Army (or any other army) would go with two different loadings?
