Put a 140 Berger at 2800fps up against the Roberts and tell me the difference. Or a 147 ELD. Or a 139 Scenar. Or a 143ELD. Or a 136 Scenar......
Since my posts have had to do with "most" hunters - the vast majority of whom use factory ammo - and ranges of 300 yards or under, how about just comparing factory ammo such hunters might actually use?
Using 'Point Blank' again, 50F, 7500', 300 yards, 10mph drift:

Granted, the Creedmoor comes in best in this list, but many of the differences are very small compared to typical kill zone sizes. And, as the list shows, hunters could easily end up worse off in terms of drift depending on which Creedmoor ammo they choose.
Oh, and the comparison to my .257 Roberts handload you asked for?
.257 Roberts +P handload
4.80", Nosler 110g AB, B.C. .418 B.C. @ 3163fps, 22" barrel
At 300 yards it beats half the 6.5 Creedmoor factory loads in terms of drift. Because I don't like frangible match bullets for hunting, it beats all of the 6.5 Creedmoor loads I would use for that purpose.
