I have found that, generally speaking, the .270 is more inherently accurate than a 30-06. Nice thing about quite a few .270's is that they will print every bullet weight, from 100 grains through 160 grains (with full power loads), so close the same spot at 100 yards that no sight adjustment is necessary.

My current .270 is an Ackley Improved with a Shilen 1:10 26" barrel. I have seven loads developed for this gun. All of these shoot in the .6" to .8" five shot group level at 100 yards. And they all shoot to the same spot at 100 yards. With a Cryo frozen barrel and a free floated HS Precision stock, the zero never changes. Kind of boringly efficient . . . .
