I am working with a 280AI at the moment with a 22" barrel. I will post some load development work over the next few weeks. Still forming cases at present and the loading is just beginning.
Starting with 160gn Accubond's, 150gn Partitions and Ballistic tips, 145gn LRX's 110gn and 120gn TSX's, 154gn Hornady's, 140gn Woodleight's and whatever else I can find on the bench.
It will be easy to add about 25fps per inch to suit your preferences.

I had originally built my son's 280AI with a 24" barrel. After the first season we took it back to 22", handles much better, looks better and we lost a whopping 35fps, 145 LRX's still run 3150 with much Rel22.
My rifle in the above post is 23". I may take it back to 22" this winter.
