If you are going to go long action, might as well do a 6.5-06, 270, or 280.
No messing with rim sizes, low pressure load data, varying twists, throats etc.
Short action, go with 260 or Creed.
I almost had a 6.5-06 built about seven years ago but I backed away because of the rumor/myth of severe throat erosion. AND- a guy at work said, "just get a 270"
Is there something cumbersome or awkward about 6.5-Swede bolt faces and rims sizes or something? I have never owned one. Heck-never actually seen one in person.
Does the 260AI solve some of slight (longer heavier bullet) disadvantages of the 260?
Had another friend at work that stumbled upon a ruger walking varminter they had back then in 25-06. First gun he ever learned to reload for and that thing was a tack driver. That was a long time ago, but the idea of a lazer beam trajectory and little recoil kinda stayed in my head all these years.
