New Army "Caliber Configuration Study"

[stanc]

My prediction is that we'll see a proper military spec lead-free 6.5 mm bullet developed for the Grendel 6.5 x 39 mm case and also for a necked-down 7.62 x 51 mm case.

As in 6.5x47 Lapua?

While the merits of a round that fits legacy weapons are hard to argue against, I still like the idea of an optimised case with growth potential that allows both tracer rounds to be fitted and an eventual move to polymer technology.

Yes, the probable reduction in powder capacity with a polymer case does argue for a cartridge case longer than that of 6.5 Grendel.

It should be interesting to see what comes out of the CCS. Any word on when that study is to conclude?
