ANY caliber bullet CAN be designed for a desired BC, but some just haven’t yet. The SAAMI specified twist rate for the .270 Win and Wby are 1:10 so no really high BC bullets were designed for them simply because they won’t stabilize them. High BC .277 bullets are starting to show up now, thanks largely to new cartridges that have a fast enough twist rate to accommodate them, but they still haven’t caught up to the 6.5s, 7s or .308s yet. I predict we’ll be there before long.
