Barrel life is conditional on number of shots, how fast fired making the barrel hot and erroding the throat area. The throat is what goes looooooong before any rifling wear. Many times, improper over zelous cleaning ruins more bores than rounds fired. Just a rough estimate, expect at least 1500 to 2000 rounds before the barrel accuracy falls off. On a hunting rifle, that's a number of years for minute of deer accuracy. From a long range bench gun, could be toast in a year if it will no longer hold tight groups, so you see accuracy is subjective. Good barrels can be had from Sharp Shooter Supply, Northlander and Sinarms, all site sponsors here.
