Tracer projectiles (for rifle/m.g. cartridges) are nearly always -- if not always -- signifcantly longer than ball bullets. If you make the ball round 5.8 L/D, what will a matching tracer be? 6.8? 7.8?
Another thing to consider: Bullets of <5.0 L/D already eat up substantial powder volume in the Grendel case.
Increase L/D to 5.4-5.8 and capacity will be cut even more.
