New Army "Caliber Configuration Study"

[stanc]

Caliber doesn't matter — 6.8, 6.5, 6.35, 7, whatever — it's the performance that counts.

I totally agree with that.

Regarding, the ABGL, you make a high-velocity 40mm by making it recoilless. That's why I suggested a "mini" Carl Gustav-type technology that would look similar to a Russian RPG launcher, except the grenade cartridges would be loaded internally, like a bolt-action.

You put the electronics in a sleek nose cone for a higher BC.

I've often wondered what ballistic improvement would result by putting a long, streamlined ogive on the 40mm grenade.

FWIW: 20mm Carl Gustav
