They haven't actually dropped it, they novated it, which means they've given up the rights temporarily, it will come back to them at some point in the future

I don't really see the advantage of a case telescoped round for an infantry weapon when compared to TV's polymer cased one.  It would seem:

1)  that more polymer would be needed to enclose the bullet, increasing the rounds volume

2)  the case would be larger diameter (although shorter), making the magazines wider and the increased volume adds bulk

The dimensional difference between the two are not that great.

The 6.8 TVCM has the same diameter and length as 7.62 NATO.

The 6.8 CT has insignificant difference in diameter and length.

There's little difference in cartridge volume, magazine size/bulk.

Why do you think it is temporary?

Because the Army and GD specifically used the word "Novated", which by definition is a temporary lease of patent rights to a lessee (in this case TV/LSFW)

Ah, thank you for pointing that out Stan about it being black.

Last night I downloaded this software extension for Chrome to make every website I visit appear in “night mode,” which is a darkened screen designed to be easier on the eyes when reading at night.

I guess for some reason this “night mode”is getting copied with the text, and blacking out quotes. I’ll try and get that figured out; using my phone now.

Testing testing. Whitelisisted delphiforums, hopefully that fixes the blacked out quotes.

It may sound childish, but I just cannot bring myself to care about SIG's bid other than hoping it doesn't win/get adopted, They're only in due to rules lawyering the requirements and all they offer is dead end technology

Their LMG looks pretty good, so long as accuracy is ok (an earlier video had mentioned pretty poor accuracy, possibly due to the moving barrel.)

As far as SIGs case technology, I'm torn. I dont like it for 6.8, as the result is a 7.62 weight cartridge - obviously not great.

But, SIGs case could be really sweet indeed in a smaller cartridge.

For example, I'd be very curious to know how the velocity would be for a 6x45mm (5.56 necked up to 6mm) would perform at 80kpsi firing a 85-88gr projectile at 2.5" COL. With the SIG high pressure case, you could get a 'GPC' type performance out of a metallic cartridge not much heavier than 5.56 brass. 

Likewise, a .224 Valkrie at 80kpsi... 

This of course supposes that TV's cases may not be optimized for high pressures. On the other hand, if TV's cases can run 80kpsi no issue, then SIGs cases are indeed pretty pointless.
