Zero, read the second paragraph of my post. I would bet you are loading .280 AI to substantially higher chamber pressure than anything in the books for .280 Remington.
There was a fad a few years ago for building custom Mausers in .280 Rem because the gunsmith could put his time into making it look pretty instead of opening up the bolt face and magazine for 7mm RM. So the practicioners went to the trouble of reforming Winchester .270 cases to .280 because they were harder brass and would not show "pressure signs" as soon as the right headstamped stuff when overloaded.
As to your PM on powder choice, I had another guy tell me with a straight face that that product gave less recoil than anything else loaded to the same velocity.
