6.5 x 40 New AR varient

[cory]

I don't know why we keep perpetuating this rumor that there is some problem with getting links for the Grendel case. There's a link somewhere in this section of the forum to another forum where a guy used, the rpd links I believe, and he states it was like the links were made for the Grendel case.

What I see here is the Grendel, a mild case that is limited by the platform, compared to a 6.5 case that's being hot rodded. With the new DPMS GII platform or upcoming Desert Tech DMR, it would be a relatively simple process to machine a bolt to the .308 external dimensions with a bolt face to accept a Grendel case.

Until we see substantially more data on this new 6.5 cartridge, I'm going to be extremely skeptical of it.

JASmith has made valid points to the potential of a problem with the current 6.5mm projectiles against body armor. However, we've design projectiles and loads for the 5.56 NATO, 6.8 SPC II, and 7.62 NATO that can defeat body armor. I find it hard to believe that a projectile in the 95gr-107gr range with the right load couldn't be developed that would sufficiently meet this requirement, especially if we could operate the Grendel at 58ksi safely.
