Optimized Caliber

[Variable]

Yes, but that would not be representative of the weight when configured for military use.

For instance, the SR25 EMC weighs 8.3 lbs.



I wholeheartedly agree the concept needs to be demonstrated.

The question is, which approach would give best overall results?

a. Your's - 5.56 NATO for carbine, 6.5 Super G for LMG, DMR.

b. John's - 6.5 Grendel for carbine, LMG, DMR.

c. Tony's - 6.35/6.5/6.8 GPC for rifle, GPMG, DMR.

Without a wealthy backer with cnc machines, my vote would be "B". Super Grendel would probably be best, but what doesn't exist can't be demonstrated.

Everything is a series of compromises in one form or another, and while I'd like to see a "Super Grendel", I think the current form is sufficient for use across the board.

ETA: I should say that what LRRPF52 said about 5.56 for carbines is spot on. But considering what kind of enviro hoops they are probably going to put the 5.56 ammo through--- I'd just say the heck with it and go Grendel to retain lethality. From a logistics standpoint it would be rather advantageous for one cartridge to cover it all. I'd be willing to take the hit on overall loadout quantity in exchange for increased lethality and penetration from short barrels at various ranges, not just up close.
