Berger did this on purpose. They said that .270 bullets would mostly be used in hunting rifles (vs target rifles throated for the purpose) so made the bullet so it would be more likely to be closer to the lands in a factory .270 rifle to improve accuracy vs making as streamlined as possible as they did for 7mm/.264. The only other place where 7mm bullets are more streamlined in same weight is the 140 nosler btip vs 140 277 btip. The majority of makers have .277 bullets of the same weight with higher BC than 7mm as expected due to higher SD.
