Have to know what chamber.
Basically, the more powder you are burning, the shorter the life. A 223 has about 6 times the barrel life of a 22-250.

Actually, the barrel starts to "open up" after the first round, and continues to do so.
Cartridges with the performance you mentioned, will give you ~2,000 rounds of usable barrel life IF YOU ARE CAREFUL...
If you go to a prairie dog town, all estimates are void (along with the barrel life).

It's not the speed of the bullet that causes barrel wear, it's the higher powder charges required to push the bullet faster. More powder = longer flame time = higher barrel temeratures = more throat wear.
Think of it like welding, when you place the flame to the cold metal, it takes time to heat the metal so you can weld. Once the metal is hot, it takes less flame time to reheat it enough to weld. That's why Catshooter said "If you go to a prairie dog town, all estimates are void (along with the barrel life)". On a smoking hot barrel, you are causing expotentially more barrel damage with each shot.
If it was just bullet speed that wore out the barrel, the wear would be at the muzzle as that is the point of highest bullet speeds.

The longer the throat is exposed to the flame, the more damage is done... which is why heavy loads of slow burning powder (with heavy bullets) will burn a throat faster than heavy loads with light bullets.

Heat/pressure/time
Also, no one ever thinks of how long the leade is to begin with which is a major factor.
