I had my suspicions. Folks who load the 280AI tend to firewall it so commonly recommended loads are often hot.

I don't load the 280AI but I do load the 308 so I can give a pertinent example there. Suppose someone asks me for a top load with a 168 grain bullet. Well my 308 really likes 46 gr. RL15 under a 168 Nosler CC in WW brass which is thin, capacious and tough. But all I tell them is "46 of RL15" and they go stick that straight into the soft, thick lower capacity Nosler brass they just bought. Any guesses as to what will happen? You wouldn't be guessing because you already saw it in your 280AI.
