Does the 6.5 grendel have the potential to replace the 5.56 for the military?

Of all the comments, I must admit that my buddy LRRP52 has the best view of it. You don't need to get something to replace the 5.56 but maybe, just maybe, something like the Grendel can replace the 7.62.

Gene, do you mean replace 7.62 across the board (infantry, armor, aviation, etc), or just in a LMG for infantry use (as per the 1970s 6mm SAW)?

Like a 6.8 SPC shooting a 140 grain bullet!

Methinks you jest, but 6.8 SPC actually could be a viable option. Since at least 1892, whenever a new cartridge has been adopted, so has a new rifle to fire it. Therefore, there is no real need to stick with the COAL of 5.56 NATO. Increase the overall length of 6.8 SPC so that it can take a long-ogive projectile, and it ought to deliver about the same "reach" as 6.5 Grendel.

Plus, 6.8 disintegrating links already exist. :eek: (Sorry, John. I just couldn't resist. :o)
