I'd rather have a short action than a long one, but if I had some only long action Model 700 laying around and in need of a barrel swap, I'd probably go .260 Remington in it, but set it up to accommodate a longer than S.A.M.M.I spec O.A.L.
The next step up from there would be .256 Newton / 6.5mm-06 but that would be an unlikely one.
On the .260 Rem vs Creedmore question, one way to solve the conundrum is to just get a .260 with a 3" mag box.
Just curious as to your comment on the 6.5-06, why is that unlikely? Seems to me to be the best of both worlds, easy to load for, and cheap brass too.
