RE: Have you bought a 280 recently?
It can easily outperform either of those rounds you mentioned, however it didn't sufficiently distinguish itself form the rest of the field mainly due to a series of unfortunate marketing snafus. I'm still a firm believer that it is capable of consistenly outperforming either the .270 or the .30-06. The factory loads, tame as they are, are still marginally better than most of the .270 and 06 offerings.
