New Cartridge Developments and Implications for Dismounted Infantry Soldiers

[stanc]

I think the polymer mag and AR magwell limitations can be dealt with using a mag body that gets wider outside the magwell, while allowing for higher capacity as well.

Doesn't that typically result in a more complicated and costly mag?

A metal mag with the same approach could be another solution.

Perhaps SureFire should be talked to?

Either way, it would be nice to have mags with a body that allowed longer COAL.

The 6.8 guys like PRI mags for that reason. PRI mags have the two halves butt-welded together in front, whereas other designs overlap and spot weld. I wonder if PRI is too devoted to 6.8 SPC to consider making Grendel mags?

As far as brass and bullets go, the new Hornady brass seems to be going through some teething issues when it comes to fitting in certain chambers...

What R&D can 65grendel forum members do about that?

...and there is probably a little room to develop an optimized line of projectiles for the Grendel.

Yeah. IIRC, there are only two or three bullets that were designed specifically for 6.5 Grendel. Cartridge-specific 110gr TSX and 85gr TSX were made for 6.8 SPC; TSX's in those weights would also benefit 6.5 Grendel more than the 120gr TSX, which I think was created for higher-velocity rounds like .260 Remington.
