How could or should the 6.5 mm Grendel be improved?

Guardsman, that is the most succinct and lucid argument for an intermediate caliber that I have hear.

Thanks!

I'm not sure about that, but thanks anyway!

I am a real fan of the Grendel - it's the best attempt to produce an intermediate cartridge since the UK 6.25 mm and US 6 mm SAW of the 1970s - and outperforms both in a smaller package. If it were adopted tomorrow, I'd be delighted. But for that to happen it will need further development...
