Looking for Hornady 280, 150 grain ELD-X.
The .280 is longer from the base to the shoulder than the .30-06. Remington's ads compared it to the .270 Win. in performance, so they wanted to make sure someone could not chamber it in a .270. There is a wildcat called the 7-06 which is a .30-06 necked down to 7mm.If I remember right you can make .280 brass by necking down 30/06 brass
