Seems the US Army is steering away from the 5.56 MM chambering in favor of the 6.8MM. Reasons given were "Improved lethalaty at longer range against targets wearing improved body armor, and a marked increase in accuracy at longer range.

Sad to break the news to you .270 Win haters, but it's a .270 Win loaded with a 115 projectile.

Are you talking about the 6.8x51 (.277 Sig Fury)? Not sure how I feel about a three piece cartridge case that uses an aluminum disk to hold a brass body in a stainless steel head all so it can run at something like 80K PSI.

Those pressures are terrifying but I'm assuming they did that to get the velocities needed to accomplish enough energy to punch through the sand peoples improvised armor.

Seems like that did this a few years ago…. 6.8 SPC.

Fully decked out new Sig rig comes in north of 10Lbs.
question is will today's infantry personnel be able to carry it an ENTIRE 1/4 mile?

The Picatinny rail isn't for putting optics on top of the rifle; it's for attaching the rifle to the bottom of a drone.

Ten pound individual rifles. . .full power ammo. . .interoperable ammo between individual rifle and squad guns. . .it seems I've heard of this concept before. . .
I'd like to see some comparison testing between this new round and good old black tip .30-06 AP. .303 Brit MKVIII, and some of the better 8x57 and 7.62X54R loads. I sense there might be more than a few "Nice try, Cupcake" moments.

Actually, I christened it the ".270 Short" in order to get under someone's skin....in any event. It's still a damn fine coyote rifle r

Speaking of which, where the hell is Snake?

That's what your buddy is for.

You know Linefinder, if you remember about 20 years ago on the old Guns & Ammo forum, we debated the best overall bullet caliber. Consensus agreed something in the range, of 6.5 mm would be the perfect caliber bullet. The debate was driven by GunnyRagg and Jim Rice, so if anyone was going to contribute, they had better bring their "A" game. The debate was spirited and in the end there was aggrement.
What is amazes me is that for 100 years this caliber has stood up as an extremely viable choice. Everything old is new again.

Bounces off squirrels.

Put ammo in that bad boy and you're going OVER 10 pounds. Add optics another half pound or more. It's a fine rifle, I just don't see it beyond a designated marksman rifle, regardless of plans to adopt. The Marines go to a Sig 5.56 and doo quite well with it. The M 4 may be finished, but it's going to go slowly.

The forgotten weapons dude did an AMAZING video about this.

It's deja moo all over again!

So exactly what is the problem with 3006?
A new round requires completely new manufacturing tooling. Same for the rifle.
Oh! Now I remember taxpayers cover the cost of development and production. Why not shorten the Garrand barrel and add modern stock?

Imagine if they just hot loaded .308 with a 120-140gr non expanding copper/gilding metal bullet. Im guessing they would get the same desired results.

I think I'm with you on that. I like the idea of a larger caliber, heavier bullet for killing people in a combat situation. The problem is the larger case as far as needing to hump the ammo. I would think that something in the range of the 6PPC case with a .308 or .277 bullet.

main problem with just hot rodding an existing round is the fact that SOMEBODY'S going to put that hot rodded 308 in an existing firearm chambered for it and damage it, or worse, get injured.
There's not a "standard" 270-08/6.8-08 to mischamber the fury in. If it fits in a standard 308 or 7-08 chamber, probably not going to be an issue since you're shooting a bullet that's 0.007" (or more) undersized.
