Serbia adopting 6.5 Grendel as main military cartridge

Robert, the right solution is the right solution, although I don't know if going shorter than, oh, 1.25" is necessary.

It remains to be seen if the 93-grain bullet OAL is actually shorter than, say, the PPU 110-grain FMJ.
Cannelure-to-tip length is almost certainly unchanged, but it's possible that the base is shortened.
Think similar to the difference between the 7N22 (below, left) and 7N24 projectiles (below, right).

And, as you know, the nose needs to be the very best hybrid Von Karman ogive they can muster.

Um, you're conflating how you think it should be, with how the Serbian army thinks it should be.
