I would choose it because of the Lapua brass and improved case design (longer neck, small rifle primers).
Does that make enough difference to choose it over a 260?
It would to me.
Lapua is making Palma 308 cases... 308 Win w/ small primer pockets. There is your quality 260 brass.
I've been debating this same issue in my mind as well. I'm leaning 6.5x55 Swede, but I have a Mauser rather than short action. If I had a short action I think I'd go 260 Rem, personally.
