The WSM does slightly outperform the Remmington magnum ifthat is what you are looking for.
If you are hunting Texas whitetails another 280 would be a good pick also.
Only according to the browning and winchester advertising.The cartridge capacities are pretty much equal,and when you consider thatmost 7mmremmags have longer barrels than the factory 7mmwsm's,the 7mmremmag may even havethe advantage.
