.270 180 Woodleigh BC .513 does correctly stabilise with 1:10

Yep.

most people use common twists with common bullet weights and get the job done at most common ranges.

Im a 7mm fan , but the hype about 280 AI and better bullet choices is exaggerated, as are some muzzle velocity claims.
ie; I doubt some are based on 'safe' loads or common length barrels.
