I’d say its superior by about .5mm frontal area(8% more?) and 20 grains mass(14% more?). So yes, I’d say it’s probably ~15% better all else considered equal.
You could go the opposite direction and look at the 240 weatherby. I think folks would agree it’s a lesser elk round than the 6.5 and the 7mm.
None of that shows up in killing animals. Ironically, last year 8 elk were killed with a 6mm last and all 8 died quicker than any we have killed with 30 cal mags with same placement. One of those the 6mm was used to kill an elk at 970 yards that had been wounded with three rounds from a 300 PRC. Does that mean a 6mm is “better” than a 300 mag? No. It means that almost no one has killed and seen enough elk killed with bullets from .22-.338 to see any real difference between them.
As for 6.5’s on elk past 600…. In the last couple of years I have seen or killed myself over 20 elk with 6.5’s past 600 yards. None of them were special- elk were shot in the front half and died as they do with anything else.
