i never make misteakes.
Yes the two cartridges are almost identical in terms of ballistics. They fire the same bullets the same speeds. The difference is in the case shape. The .260 is a necked down .308 and can be used in any short action that the .308 can. The 6.5x55 swed is just a little to long for short action.
I will add more stuff to this topic after work, got lots more data on this topic.

The .260remington also known as the 6.5-08 A-Square.
Inclusion of this cartridge presents us with a bit of a problem. long about 1996, A-Square, a bonafide member of SAAMI, submitted drawings, chambering specifications, chambering reamers, sample cartridges and all other necessary materials and data describing a new factory chambering to be adopted into the SAAMI fold. A-Square requested that the chambering be named the "6.5-08 A-Square," as specified on the sample cartridge headstamp. Many months later, Remington submitted a memo to SAMI wherin it mentioned that it intended to eventually standardize a 6.5mm version of the .308winchester as the 260remington. Since SAAMI subsequently chose to christen this chambering as "260 Remington," a disinterested observer would have to conclude that something was a bit rank, somewhere.
(I personally would say that whoever made that desicion was smart, knowing that the general gun public would probably be more consumer confedent with a cartridge named a Remington rather than an A-Square)
This cartridge has precisely two things to recommend it. First, it is a superior choice for long-range target shooting, particualarly in the NRA Highpower game, where reduced recoil with lighter bullets is valuable for the shorter-range events and where barrel life is an issue - a serious competitor can wear out several barrels each year. Second, for those who want or need a very light hunting rifle and are honest enought to admit that they cannot toerate much recoil, this chambering is a superios choice. Hunting load ballistics far exceed what the .243win can produce but are not insurmountably far behind the 7mm-08rem. Nevertheless, this would seen to be a minimal chambering for use on any North American big game. Those intending to use this cartridge for elk hunting should consider on hte best premium bullets, such as bonded-core and partition designs and the 100-grain Barnes X (which will penetrate futher than most 120-140gr premium bullets).

I'm kinda pondering getting a Tikka Whitetail Battue in the .260rem for around here. I just wish there was a way to put something on the reciever that wouldn't obstruct the sights so you could use stipper clips on it.
