Apples to apples, meaning ABLR's across the board and using Brian Litz's .277 BC of .543, the 270wsm would have 21" more drop, 6" more drift at 800. 7mm Mag would have 7" more drop and about an inch less drift with 150 ABLRs.

Assuming all the other BC's hold and Noslers own data (3,240 7RM and 3,150 270WSM) is attainable.
