I don't see that being a reason to not evaluate the Grendel as it currently exists, just as a proof of concept.

But, since 6.5 EPR is not available, valid comparative testing could be done using PPU 6.5 FMJ vs 7.62 FMJ and 5.56 FMJ.
LR1955 Wrote:People tout Serbia as using something less powerful than a Grendel. Serbia is also not a strategic power. They do not project power into places other than Serbia so their equipment designs are focused on their terrain, structures, climate. A 6.5 X 39 is probably a step up from the 80 year old 7.62 X 39 and may be fine for them but I would not accept something Serbia thought was a good idea for their Army unless our people gave it a formal and scientifically grounded series of tests based on our requirements.I agree that what caliber the Serbian Army opts to use for its small arms is not necessarily relevant to US requirements. However, since our military does project power around the globe, the idea that 6.5 Grendel promises 7.62 performance from machine guns and rifles of 5.56 weight, it seems like the Horde's favorite cartridge would be worth considering... .providing that it can be demonstrated to actually deliver the promised performance.
