NO, it isn't. At least, not if you load your own ammo for the 7 Mag. The 7 Mag. has two basic advantages overthe .270round: It holds more powder; it shoots larger-diamter bullets. Both of these work together to provide the potential for higher velocities with bullets of equal or greater ballistic efficiency. These factors work together to provide both a flatter trajectory and more down-range energy.

The ONLY advantage I see to the WSM or SAUM's is they can be used in a shorter action (lighter rifle). This is generally mox-nix to me, because I mostlyhunt with a single-shot anyway, so length of the round doesn't matter.
