They call it that because it has an air pocket at the tip, causing it to be wildly unstable after it hits virtually anything

You don't think it might have something to do with the roughly three fold increase in length of the Russian round?

You mean like a Sierra 70 Grain MatchKing?

Yes, I am sure that greater case capacity is certainly important...but I was only addressing the bullet design. I think more case capacity would vastly improve effectiveness, but so would better chemistry, and/or switching to a larger diameter bullet. I just don't forsee our military changing our ammo that much, unfortunately, and so it would seem that improving interior ballistics is the way to go. Making the barrel shorter will only decrease performance, if not compensated for elsewhere.
