I agree, there is no clear answer, it is matter of personal choice. I think in bolt gun the 7mm-08 has the advantage because of the shorter stroke and stiffer receiver. In a single shot that is all out the window because the case length is not going to be a problem. In the Handi particularly you get a 26" barrel. If you hand load, you can load it down to 7mm-08 levels and up to the full bore 280 loads, which by the way are not too short of the 7mm Rem Mag. I love the 7mm-08, but in a Handi I would take the 280.
