Having said that I shoot 2 6.5's both swedes and have found them both great for target work and the other great fro hunting as Jack stated if I was to pick again it would be the 6.5x47 but bugger me the brass is expensive and so the swede being the cheapest of the 6.5 crew still lives @ my place LMAO
6.5mm Cartridges - Comparative Ballistics Performance by Zak Smith
Put in order of ballistic performance, the 6.5 Creedmoor and the .260 Remington are almost neck-and-neck, pushing the same weight bullets at about the same velocities from almost identical case capacities. The 6.5×47 Lapua in factory form lags by 100 to 200 fps due to less powder capacity; however, it has already gained a reputation for having a strong case that puts up with the high pressures some reloaders push in their custom rifles. The .260 Remington’s main problem for the reloader is lack of high-quality and affordable brass and to date there has only been one factory load produced which was appropriate for serious long-range competition for the non-reloader. The 6.5×47 was designed for intermediate-range competition and very accurate ammunition is available from Lapua; however, these factory loads are at a ballistic disadvantage at long range compared to the .260 Remington and the 6.5 Creedmoor.
There will always be those who bash new cartridges, claiming that they don’t do anything better than their favorite cartridge. By this logic, we’d all be shooting .30-06. Put simply, the 6.5 Creedmoor is what the .260 Remington should have been. It looks like Hornady has the right mind-set to make its new cartridge a success in the competitive and practical market, unlike Remington who basically let the .260 languish in a few hunting rifles. The 6.5 Creedmoor enjoys additional case capacity over the 6.5×47 Lapua, which allows better ballistics at a lower peak chamber pressure.
6.5 Creedmoor vs. the .308 Winchester
In the first article above, Zak explains: “Why 6.5 mm instead of .30 caliber? Put simply, they sling the long, slim, high-BC 6.5 mm bullets at respectable velocity. It duplicates or beats the .300 Win Mag’s trajectory with less recoil than a .308 Win. Compared to the 175 Sierra MK fired from a .308 Win, the 6.5 mm will have 27% less wind drift and about 10 MOA less drop at 1000 yards. Despite a 35-grain deficit in bullet mass, the 6.5 Creedmoor will retain 18% more energy and hit the target 260 fps faster.”

There is factory ammunition for the 6.5x55 but availability and variety will be limited.
The .260 is be a similar story, though not quite as bad as the 6.5x55 as it is a longer established, more widely used cartridge.
Broadly speaking we have a relatively small number of cartridges that are "common", and we have "the rest".
If you're shooting cartridges like (but not limited to) the 300WM, .308, .270, .243, .223 and a handful of others you can walk into any gun store and they'll likely have half a dozen factory options and plenty of reloading components in stock.
If you're shooting any of "the rest", factory ammo and reloading components won't be kept at the same levels in stores and you would plan to either grab things when you can, or special order as required.
