It’s so infuriating that the Army wasted a real opportunity to replace 5.56 with something that has better ballistics but kept the advantages of the SCHV concept.Sorry, technical term. I don't mean the paper manuals.
I mean drill movements. Same thing the Brits and French had to do when they adopted the SA80 and FAMAS.
There are new efficiencies in there, but yes the primary driver was terminal effect. You'd kinda expect that for almost any cartridge, but especially military.
It drops less than 7.62x51 so it's easier to get hits with at varying ranges.
Because the US military "understood" that Russia etc was going to be issuing that superheavy armor to every infantryman, just like how the US issued SAPI/ESAPI etc to every single soldier.
Clear back in the 1940s or 50s, the UK figured out that 7mm 140gr at ~2400fps was just about ideal for a 0-600m cartridge to replace the .303.
For that matter, the 6.5 Arisaka and 6.5 M-S were also throwing 140gr at 2400fps, even the 6.5x55 Swede (military loading).
But yes, the NGSW specs to outrange the Afghans have been known to be bullshit for a long, long time.
6mm SAW was pushing 105 grains at ~2500fps with IIRC ~45,000psi of pressure. Imagine what’s possible with modern propellents, stainless steel or polymer cases, & 20,000psi pressure bump.
