The 7MM STW is flatter. Shoots faster, hits harder, Kicks harder cost more . However the 280 will do that same job, drop a deer at 400 yards just as well as any of the thunder cannons. To me shooting beyond 400 yards at any game animal is not an option so there is no need for a bunch of unecessary noise, recoil and expense. I have learned that for me enough is enough. The 270 and 280 will deliever around 1500 lbs ME at 400 yards. Do you need more? No. Can you have more if you wany? Of course thats what they make gun powder for. When they say it offers nothing more they mean dead is dead. That with 2200 lbs ME or 1600 ME. If that is not enough power though I quess we could use the Warbird with its 168 grain X bullet at 3700 fps. Or wait another year or so until that one is a peashooter as well. After that the 7mm-08, 280, 270. and the other little guns will still be dropping big game in their tracks as they have for many years. Good hunting guys. If I was to get a 7mm Mag it would be the Winchester Coyote in 7MM WSM.
