I have a 6.5mm Obermeyer barrel with the 1-8.75 twist mounted up on a Defiance Machine Defender action in 260 Remington. Boots is correct that it shoots the 140-144 grain bullets just fine, and also shoots the 123 grain Scenar bullets fabulously well. I switch back and forth depending more on availability rather than how they shoot because both shoot equally well. With my 260 the velocity I get, the bullet doesn't go transonic till way past (1500 yards or so) any where I want to shoot.
I went with that cartridge after considering the 6.5-284, 6.5-08 AI because after all the effort, and increased throat erosion the plain old 260 shot way further than I needed without all the extra work to form brass, or without having yet another rifle that eats barrels incredibly fast. I considered how far I really thought I would need to shoot. If I only need to shoot 1200 yards, why do I need a rifle that shoots 1700 yards and eats barrels?
