"After carrying the M16 or one of its cousins across the globe for more than half a century,
soldiers could get a peek at a new prototype assault rifle that fires a larger round by 2020.

Army researchers are testing half a dozen ammunition variants in 'intermediate calibers,' which
falls between the current 7.62 mm and 5.56 mm rounds, to create a new light machine gun and inform
the next-generation individual assault rifle/round combo.

The weapon designs being tested will be 'unconventional,' officials said, and likely not one that
is currently commercially available.

Some intermediate calibers being tested include the .260 Remington, 6.5 Creedmoor, .264 USA as
well as other non-commercial intermediate calibers, including cased telescoped ammo, Army officials
said.

If selected by senior leaders, the weapon could resolve a close-quarters weapons debate about
calibers that critics say dates to the 1920s and has influenced military small arms ever since.

If successful, the new rifle and round combination would give troops a weapon they can carry with
about the same number of rounds as the current 5.56 mm but with greater range and accuracy in
their firepower — with little change in weight.

The new rifle would likely replace the M16/M4 platform, which has been in the hands of troops
since the 1960s and undergone multiple modifications and upgrades."

The military contactors in Iraq and Afghanistan used the 6.8 SPC with good results. The M-14 was used extensively by our troops because the 5.56 couldn't reach out 1000 yards and take out the enemy.
Sounds like we may have a new caliber coming out soon.

I am always wondering since the military doesn't reload, why don't they develop a lighter weight casing material  to allow heavier/more projectiles per combat loadout.

Seems like actual combat ammo could be easily done in aluminum, magnesium, titanium or possible even teflon, drastically reducing weight.

Actually polymer [plastic] cased cartridges have been in development since the early 2000's. I think the Picatinny Arsenal in NJ was working on that.

Cheaper & lighter.
