Alternative to 6.5 Grendel?

[cory]

...Also, keeping the 5.56x45 cartridge case has manufacturing and logistical advantages, in addition to the end user benefits noted.

Your thoughts?

I disagree. If the 5.56 is ever replaced, there will need to be senators behind the push, so we have to think politics. In order to get a senator behind this and/or their vote you'll need to convince them that it'll bring jobs to their district. Therefore, a change in the LC machinery, brass and magazines would have more of a chance of getting funded.
