RE: .270 too light for elk?
My .02 is the .270 Winchester would be my minimum. With some of the great bullet choices we have now it makes it amore viable choice.
Personally I have always used one of my 300 win mags or 300 wsm's and if I were buying a rifle specific for elk it would not be a 270 win.
The 270 wsm would be a better choice yet over the std 270 win. IMO
