The question was about the need to engage at 600 meters.

That I don't know.

I think you have missed my point about the logistics of 6.5x48 mm Creedmoor ammunition versus the logistics of 6.8x51 mm NGSW. I estimate that the latter system will cost 30-40% more than 6.5x48 mm Creedmoor. 10% would be significant, but anything above 20% will kill NGSW.

And that would be bad, how?

The question was not about terminal effects at 600 meters.  The question was about the need to engage at 600 meters.

The need for infantry to "engage" at 600 m (or up) is mostly a byproduct of the Rules of Engagement, but even with liberal RoE, the infantry needs to fix the enemy.

What if you resort to higher pressures, but not NGSW high?

What barrel length are you comfortable with?

SIG's 6.8x51 mm pressure seems to be the price to pay for a 13" barrel instead of 19", or a 16" barrel instead of 22".

Okay, but I'm not seeing how that answers either of Nick's questions:

"How important is the need to engage enemy targets at 600 metres?"

"How often will we need to engage enemies at this range?"

At the 12:45 we have FA testing of the SPEAR at 50yd; actually looks very good in terms of controllability and burst accuracy at that distance.

The 'flow-through' suppressor also seems to be working well; no gas to the shooters face, and pretty compact.

It does look pretty good.  Brass-cased (lower power) ammo, though -- not the full-power hybrid stuff.

Ah, great eye Stan. 

That brings up a pretty interesting feature; it seems like the Spear can fire both standard (62ish) pressure rounds, as well as the 80kpsi high pressure rounds. 

I wonder whether this requires changing the gas setting, and if there is a dedicated setting for both types of ammo?

That just mean that depending on your RoE, engaging enemy targets at 600 m (or higher) could be rare and few (like during WWII & Korea), or up to one quarter (25%) of the infantry engagements (like Afghanistan).

That also mean that in the first case, issuing a DMR is probably sufficient to deal with those "rare & few" events, but in the second case you will probably need a NGSW.
