The machines can swage or machine any nose profile you care to design.That would seem to be true, provided the bullets are the same weight. For instance, the BCs of the 150gr .308 Sierra FMJBT and MatchKing bullets are virtually the same at velocities over 1800 fps.
However, IIRC discussions on Tony's MG&A forum, consensus was that a lead-free 6.5mm ball projectile would be limited to a maximum weight of ~110gr, due to length and stability factors. If the cited trade study looked at 123gr match bullets, there would be a substantial difference in BCs relative to a 100-110gr ball round.
