The 6.5x55 is ballistically superior to the .308 Win, but that's not real hard. After about 600 yards or so (with suitable long-range bullets) the Swede pulls ahead in energy. This is comparing heavy, long-range match/hunting bullets (A-Max); 178-gr .30 cal and 140-gr 6.5mm. It should get around 1/2 to 2/3 the barrel life of the .308 Win., say, 2000 rounds in match shooting.
I would be leery of using the 6.5x55 on game larger than deer.
Great cartridge though.

I have hunted extensively in Alberta with both a 6.5x55 and .308. I seriously doubt you could tell the difference between the two in a typical hunting scenario. Neither of them are particularly "high velocity" rounds compared to the various 7mm mags etc. In Sweden and Norway, the 6.5x55 is a very common cartridge - similar to how the 30-06 is in North America. They shoot thousands of moose there without any problems. Keep in mind that the 6.5x55 earned its reputation as a very efficient killer using "heavy for diameter bullets" like 154 and 160 grain bullets, launched at modest velocities (in the range of 2600 fps). This combo ensured great penetration without the risk of bullet failure, in the pre-premium bullet days. In North America, you typically see the 140 grain loads as a way to sqeeze a bit more velocity out of them. Compared to the .308, you will not see any significant difference in barrel life in a HUNTING rifle. Both rifles have very modest powder charges and velocities. The only real way to burn out one of these barrels in a hurry would be to blow through a whole pile of ammo (re: auto fire) in a very short period of time, and generate an huge amount of heat.
In practical hunting terms, the average shooter will never shoot out either a 6.5x55 or a .308. Target shooters are different, but they are held to different standards as well. For 95%+ of hunting, a rifle which shoots 1.5 MOA is perfectly adequate. For target shooting, it is not. I would venture a guess that the usable (1.5 MOA) barrel life of either of the two mentioned cartridges would be in the 7000-10000 range, providing it is not abused.
For an average hunter in North America who is not a handloader, I would recommend a .308, simply due to ammunition availability. As a side note, at typical hunting ranges (<250 yards), the .308 outperforms the 6.5x55 with similar weight bullets.
