You can wear out a .270 Winchester in about 5000 rounds. Its accurate life is around the 3000 mark. Life can be exceeded or lowered depending on the quality of ammo and how lightly or heavily the case its loaded.
The Canadian Rangers replace barrels on their Lee Enfields every 10,000 rounds.
A .22LR basically can't wear out and only wear out from excessive cleaning or not cleaning enough.
A magnum cartridge, such as a 7mm Remington Magnum, can wear a barrel out in as little as 1000 rounds. Its accurate life ends about at that point and may only have acceptable hunting accuracy up to 1500 rounds.
.308 barrels are suppose to last a very long time. Its barrel life is suppose to be as high as 10,000 rounds even in a commercial bolt action rifle.
A 9mm pistol can last about 25,000 - 40,000 rounds.
A .223 accurate life is suppose to be just shy of 10,000 rounds.
In the Czech Military, the Vz 58 7.62x39 service life was set at 15,000 rounds.
Note that barrel life and accurate life are two different things. Accurate life span is how long will the firearm retain it's original new broken in barrel accuracy. Barrel life is how long a barrel will last until its accuracy is considered unacceptable.
They're are a number of variables such as type of bullet, case load, and primer.
Semi / Full auto rifles suffer from gas port erosion. Even though a barrel may still be fine, the gas port may erode to cause violent ejection and increased wear to the rest of the firearm and therefore the barrel can be considered worn out.
