I have read Remington loaded a little light for the Remington autos, but not much difference to the hand loader. I know the 7 Mag has that much "disliked" belt but I neck size my once fired so it head spaces off the shoulder.The 7MM holds one less in the magazine but not a big deal..I've never had a 280 AI but would think the standard 280 or 7 MM Express would feed more smoothly.
