Excellent choice. Although, I would say exactly the same thing, with equal conviction,if you had chosen the .30-06.
Last time I was at the rifle range, I took a walk up and down the line to see what everyone else was shooting. The .270 seemed to be the overwhelming favorite, as half of the shooters were using it. The other half were dispersed among a variety of calibers ranging from the .22 to .300 mags.
