As far as brass goes the 6.5x55 can be had in Norma, Lapua, Winchester, Remington, Nosler and Prvi that I know of. The .260 only in Remington and Nosler (correct if wrong). Unless you want to neck up or down and deal with the headstamp issue the Swede is much more accessable. These days loaded ammo is just about as easy to come by, if not more so, for the Swede as well. The Swede is still on top of all the 6.5's component wise mostly because it's been around about 120 years and used around the world, unlike the 6.5 De'Jours we see these days. Having said all that we have each caliber and there's probably not a dime's worth of difference out the muzzle.
