RE: Need your opinions on the .280
The supply of factory ammo for the .280 is the only negative for it.
If you' re a handloader, the .280 is one of the finest rounds ever manufactured. It' s everything the .270 wish it was and a little more. It' ll stand up to the 7MM magnums and do so in a featherweight fashon.
It' ll handle elk, moose, caribou, sheep, and african plains game....but it' s best if you' re a handloader.
