In a bolt gun, using handloaded ammo they are about equal. They use the same projectiles in teh same weight and velocity ranges.

Load data for the 6.5x55 is usually for the '96 action. The .260 and 6.5x55 are very similar. When you move to a '98 action or modern action for the 6.5x55 you can hot rod a bit. Most loads using IMR4831 are within 15fps, When using lighter bullets such as a 120gr and 4064 the .260 has a 40fps advantage, but that is data for the '96 action. There is no real advantage as far as perfomance between the two. The .260 is a short action, the 6.5x55 a standard. That is the difference.

Well I'm going to change the 260 to a 6.5 x 284. What's the comparison there?

Very similar rounds for sure. I just like the 6.5x55 because of its history. A super round that I hold dear. Has been around for over 100 years and will be here another 100. Killed 4 deer with the 6.5x55 last year and its light recoil, deep penetration and superb accuracy make it a winner in my book. Then I'm old and like the 7x57, .220 swift, and the .270 real well also.

When you move to teh 6.5x.284 you gain 10 more grains of water volume capacity in that particular case and can drive a bullet another few hundred FPS faster. but you will be moving into long action territory, and a longer barrel and heavier rig in the process.

6.5-.284 Norma has a short barrel life. It is known as a barrel burner.

This is typical for compitition shooters:
Barrel life is a key issue for 6.5-284 shooters, because barrels can loose their accuracy edge in as little as 800 rounds, though 1000 rounds is more typical. But don't throw away that barrel merely because the groups start opening up. Sometimes some aggressive throat polishing can restore much of the accuracy, and you can get hundreds more rounds of useful life by having the barrel set back.John Hoover reports: "I've had many barrels set back 1". Nearly always they shoot as well or better than before."

There are many different 6.5mm caliber that you can choose from. 6.5x55 Swede-260 Remington-6.5 Creedmoor-6.5x47 Lapua-6.5x284-6.5/06,and several others.
All are very capable of accurately shooting 1k yards,it really depends on what you want,and if you want to shoot factory ammo or hand-loaded ammo.

What are you planning on doing with the rifle? Hunting-Target-Long Range shooting?

Do you hand-load your ammo? If you don't,the 6.5x55 Swede would probably be the best choice,there are many different factory ammo types available for it.

I shoot the 260 Remington and 6.5 Creedmoor,and like both calibers,but I favor the 6.5 Creedmoor since you can load the longer 140gr VLD bullets and stay well within magazine length with them.
I'm planning on building a 6.5/06 AI on my 300WM action in the future for a hot rod 6.5mm long range rifle. I prefer the 6.5/06 over the 6.5x284 because I can make brass from any cartridge of the 30/06 family,and that will be a lot cheaper to do.

In factory form the 260 Rem is the better performer since nearly all 6.5x55 factory is loaded to 100+ year old Mauser pressure, in handloads the 6.5x55 has a slightly higher case capacity and can be pushed a bit faster, a friend of mine uses a modern action Swede for F-Class and he is pushing 142gr SMKs to 2950fps using RL22, I am unaware of any 260 load that will push a 142gr that fast without pressure signs.
Although factory 6.5x55 is not scorching fast it is still plenty adequate for deer hunting I have used my 139gr Prvi soft points to great effect on deer before. I can also get my 6.5x55 ammo for about half the cost of 260, my last batch of Prvi was only $13 a box, I buy them exclusively for their spectacular brass.
The 260 and 6.5 Creedmore are both short action so if you wanted to nit pick over a couple ounces of weight they would have the edge, my 6.5x55 is a 6.25lbs Tikka T3 Stainless, it is my most accurate rifle and I would not trade it for anything, it is as close to the "perfect hunting rifle" as any could ever hope to be.
