That I would disargree with.
These are the ballistics both useing 140gr Barnes X boat tail.
.270 MV 2868fps 300 yards, V= 2188fps, E= 1488fpe
.7mmRM MV 3058fps 300 yards, V= 2343fps. E= 1707fpe
Load data using IMR4831 for both. Load data from Barnes.
They are not the same at all. While the .270 drops below 1500fpe at 300 yards, the 7mm Rem Mag stretches that well past 300 yards.
