The 6.8 is being tested with 110-130 gr bullets for SOF, but they are not real happy at this point. Biggest gripe is that it is too unique. No ammo available "in country" other than SOF channels, ID's you as U.S. SOF unit when you do not want to be ID'd period. Always maintain plausible denial.
SOF is now focusing and proven that heavier match grade 5.56 bullets are more effective. The improved MK 262 Mod 1 version is using a Nosler 77 gr bullet with cannelure, loaded by Black Hills. Started out as a US Army Spec Ops Cmd (USASOC) purchase and now has been carried over to USMC. Gives 2550-2600 fps out of M4s. Proven to be good stoppper.
As they are open tip and "fragment" and not expand, the JAG rulings are that they are legal for land warfare use.
There is a 262 Mod O that uses the 77gr SMK also.
Hornady is using a 75 gr bullet in some experiments with them.
From what I have heard doubt the 6.8 will make it. Plus it would really hack NATO off as we pushed the 5.56 on them in the first place.
The USMC was looking at the 6.5 soley on the basis as it was a heavier bullet that they could load in the 5.56 case, and only have to change barrels. Ie, less cost to convert weapons currently in the system. However, the focus now seems to be on better bullets from known mftr (sierra, Nosler, Hornady) with cannelure that will penetrate and still give knockdown with MOA accuracy.
The 62 gr M855 was originally developed for the M249 SAW 20 years ago to be used against troops relatively close (200m) and wearing body armor in conventional infantry combat. The new bullets are designed for M16 and M4 use only.
Unfortunately the military develops specific bullets for specific weapons in limited roals and then someone decides that they can switch roles and weapons. Normally does not work in the new role or weapon as intended.
