barrel life

About the same as the 22-250 firing 55 gr bullets. There are a lot of variables here, type of steel and rifling, which powder being used (primers too), rate of fire, that an accurate answer is really near impossible to give. If I had to hazard a guess, roughly 5000 rounds. - dan
Generally barrel life is governed by the rate of throat erosion. Its not the bullet going down the barrel that wears it out. Large powder charges relative to bore diameter will erode a throat faster, as can high temperatures from rapid fire, etc.
Expected level of accuracy is also a factor. Serious target competition would probably require a higher standard of accuracy than big game hunting. It is not unusual for a barrel on a 6.5-.284 target rifle to be retired at 1000 rounds or so, whiile a .308 may remain competitive for 5000 to 7000.
