If your really hard on the barrels, your correct, maybe less then that even. IF you really take care of them and use them as intended , they often push close to 1000 rounds of useful long range barrel life. By using them as intended, that means never shooting more then three shot strings(preferably single shot in practical field practice situations), allowing plenty of barrel cooling time between strings, keeping them clean and use recommended loads that are relatively mild in chamber pressures.
Not saying they are by any means barrel friendly as they are not but they are not as bad as many would think if used properly. Getting two barrels made at the start is not a bad idea but if the customer has a rifle that is more volume shooting friendly to use MOST of the time and use the 338 AM for special situations that its designed for, that being +1000 yards, they will often last a lifetime and then some for big game hunting.
