Something I've been wondering about: In setting requirements for a potential replacement of 7.62 NATO, is it better to require the same trajectory and wind drift as M80 Ball, or to call for superior performance?
Achieving a flatter trajectory and less wind drift seems doable, judging by ballistics charts for the 7mm UIAC. However, the military has a lot of $$$ invested in optical sights with BDC for M80, so a strong economic argument could be made for having an exact ballistics match.
