Yessir. I've come to see barrels as expendable. I like my rifles like race cars. You won't get a lot of miles, but you'll get a LOT of fun out of the miles you do get!All it takes is taking care of the barrel by keeping it clean, keeping the pressure down to reasonable pressures, keeping the velocities below 3,000 ft/sec and allowing the barrel to cool as much as possible. Most military rifles are loaded below 3,000 ft/sec and use ball powder for longevity.
Most of the barrels you listed exceed these in one way or the other.
The 308 Is one of the cartridges that will give many years of service under these conditions.
