I thought the actual point of the 6.8 was to basically replace both the M249 and the M240 with the same weapon. Light enough to be used like a 249 but powerful enough to be used like a 240.

I'd like to know more. They claim quite a bit less recoil than the 240, even though it's half the weight.

So dumb.

6.8 has shit BC, compared to either side of it’s diameter 6.5mm and 7mm.

The longer you hang onto velocity through BC, the further your armor penetration reach is extended.

How can they be this dumb.

Bullet diameter is only tangentially related to BC.

You can design a 6.8 bullet with just as high a bc as a 6.5 bullet. It will weigh more than a similar 6.5 bullet and less than a similar 7mm bullet.

There are ways to tame recoil. Muzzle brakes, slower ROF on a constant recoil system, etc.

A ~125gr 6.8mm bullet is unlikely to have a stellar BC. If a significant portion of that 125gr bullet is tungsten, the BC may even be worse than that of a typical125gr OTM bullet with a lead core and a hollow cavity in the tip due to the tungsten AP bullet being shorter. Still shouldn't be as bad as M80 ball though.

Yup. This is what they went with, just as Russ Robinson had developed in the 40s. He, at one point, came up with a low ROF shoulder-fired beltfed .50BMG.

The higher sectional density of a 120gr 6.5mm would enhance armor penetration over 6.8mm.

The significantly higher BC of a 120gr 6.5mm will also further enhance the range, armor penetration and hit probability over a 6.8mm.

Again the Army proves it knows fuck all squared about guns.  It doesn’t even know the most basic concepts.  Like day 1 shit.

What happened to the cased telescoped round?

And why not just go with .270 short win mag instead of inventing a new round that does the same thing?

Man the army can waste money like nobody else... just watch them about-face, follow the Marines and get into the 5.56 HK416 in the end.

SIG wasn't the vendor doing cased telescoping ammo, that was another vendor.  Each vendor is responsible for coming up with their own solution to the problem of pushing the government specified projectile to the desired velocities while reducing cartridge weight.

While it may be necessary, I'm not sure going with a 7.62x51 sized cartridge will work to replace the M4, due to reduced ammunition capacities.

SIG has incorporated a recoil mitigation technology into the Next Gen belt-fed. This brings the recoil in at 2.8 lbs while an M240 in 7.62mm has a Recoil impulse of 13.1 lbs. Considering they are seeing a muzzle velocity of over 3000 FPS for a 16? barrel, this is impressive.

Well considering qual rates and stuff with the M4, probably a lot worse.

Heavier gun, heavier ammo, more recoil.

270 WSM.  Won't ever happen on a service rifle.

Any cartridge with that kinda smash will eat barrels and shoulders.  The average troop these days has never fired a gun and to toss them a weapon with 270WSM recoil and say have at would be a huge mistake.

Advanced and experienced shooters sure but rank and file grunt, sky cop etc.  It would be a huge mistake.

You have to take into account the ammo is 6.8x51. that means your running 7.62 NATO size mags, even if they're lighter....they're heavier than 5.56 and significantly more bulky in volume taken up.
