Grendel as a Universal Infantry Cartridge

[stanc]

[6.5mm] has good potential for creating a weapon system superior to those based on the 7.62 caliber when light materiel and personnel are the targets. The Grendel can be shown to be superior in many of the roles, particularly the LMG.

Perhaps. I'm still waiting to see test data that confirms it.

Hence, Tony & his debate community have been searching for and working to invent a caliber / case combination that might have enough superiority to compel a change in basic firearms cartridge in one or more major military forces. The Grendel case is, to date, the closest to satisfying the goal.

6.5 Grendel is the closest production round, but there are some experimental 6.5mm cartridges that reportedly are superior. These are essentially "stretched" versions of 6.5 Grendel. One such is a 6.5x45 being developed by Harrison.
