DEMIGOD has written a comparison of the 6.5mm rounds: the .260 Remington vs. 6.5×47 Lapua vs. 6.5 Creedmoor.
It’s been a good year for 6.5 mm. The .260 Remington has hit full stride after a ramp-up of several years, with top competitors at most field-style long-range matches shooting it. Lapua’s 6.5×47 saw the first wave of custom LR rifles built around it in 2007 and proved to be just as good as people hoped. Finally, Hornady is announcing its new 6.5 Creedmoor cartridge at SHOT 2008. How do these three mid-size 6.5 mm cartridges stack up against one another? I spent much of 2007 figuring out the answer to that question.

DEMIGOD LLC has an interesting article on the .260 Remington, a necked down .308.
The .260 Remington provides long-range ballistics conventionally limited to the magnum calibers. Because its parent case is the ubiquitous .308 Winchester, building a rifle in .260 can be as easy as fitting a new barrel. The .260 provides much less wind drift and drop than .308 but has less recoil.
The hunting pedigree of 6.5 mm in Europe proves the caliber is formidable for practical use. For long-range shooters who want a better cartridge than .308, but don’t want the costs associated with big overbore magnums, the .260 is just the ticket.
