OK. I get your point. Not "blowing by" a 25-06. I simply meant to say a 270 will do everything a 25 will and more. Basically like 2 guns in one. As far as a 280 goes, they're OK, but not by any means that much better than a 270. This being mentioned in factory configurations. A 1:8 .270 don't give up to a 1:8 280 even if you went custom. The b.c on a 170 outta that .270 is pretty good.
For an off the shelf rifle such as a tikka, rem 700, win 70, that 270 would be hard to beat for an all around rifle.
