Well, the twist and use of heavies may change that a bit. Example, an 8 twist Creed with heavies preforms well with RL-26 and slower burners.

Slower twist, lighter bullets, not so much. Older rounds generally have slower twists, are limited to lighter bullets. So, IMO, twist separates 250 from Creed more than case, etc, maybe not as much difference with similar weight bullets.
