That means the 260 is about as good as it gets in a short action.
Every heard of the 6.5 PRC?
I can open bolt faces to belted magnum diameter and get fat cartridges to feed. I did it again last month when I converted a 1908 Mauser to 300WM, but that level of effort seems out of scope for comparison to an easy short action rebarrel to 260.
