Our military adopting the Grendel?

[stanc]

Before we get a pile-on here, let me hasten to add that the 6.8 SPC was done prior to the introduction of the Mk262. That round appears to have largely rectified the perceived deficiencies in the SF and DM communities.

On the topic of specialized ammunition, I hear an awful lot of noise to the effect that the military will adopt only one style of ammunition for the infantry rifle/carbine and the LMG. And here we have at least two variants of 5.56 being used side-by-side. The same appears to be true of the 7.62X51 when sniper ammunition is issued.

Once again you are mis-stating (or have failed to comprehend) what I wrote.

I said that the US, UK, and other Armies use one bullet type and weight for general purpose, standard issue ammo.

5.56 Mk262, like 7.62 M118LR sniper ammo, is a special purpose, limited issue round.

Do armies use special purpose loads, with bullets of various types and weights? Yes, certainly, but it's limited issue, for specific mission requirements.

Do they use more than one bullet type or weight for general purpose ammo for infantry rifle/carbine and SAW/LMG? No.
