If the .280 has an advantage over the .270wsm, then I assume it would be the bullet selection ? Seems like comparing the .270 with the .270wsm would be apples to apples, and same with .280 vs 7wsm. I think flat shooting, and quick follow up shots were both mentioned, what about wind ?

Personally, my next big game rifle is going to be a Kimber Montana in 7wsm...even if I have to buy a different caliber and have it rebarreled. I have not held a Montana in my hands, but have read enough reviews to make the decision...........and they seem to move pretty well on the used market.

.30'06 ? I should buy one of those too, just too have it laying around.
