While I love my 270 WSM, I'll agree that it doesn't seem to be gaining in popularity. However, in my neck of the woods, I'd wager that 80% of the whitetail are killed with either a 270 Winchester or a 30-30. The average hunter doesn't handload, and can buy 270 Win ammo at every country store.
If the 30-30 is still hanging in there, I don't believe that 270s are going anywhere. They may never be used in competitions, but the majority of rifle owners and shooters in the U.S. have never heard of a 6BR, 6.5x284, or a 284 Shehane.
