[QUOTE="AZShooter, post: 2633107, member: 5219"] I don't worry too much about the advancing throat wear as the issue but rather a long zone down the barrel that gets fire cracked which ultimately determines when it gets replaced. The quickest I have ruined were a 6mm-284 and a 257 Weatherby right around 1000 rounds. Both were custom barrels. A bore scope shows the horror show when the barrel is on the end of its life. Not only is there significant fire cracking but there are longitudinal cracks that run parallel to the lands and grooves. The aforementioned barrels had the damaged area running up the bore more than five inches! Signs the barrel is worn out: Cleanup takes forever. Requires multiple fouling shots. After 3-5 obligatory foulers the barrel is only good for a few rounds before it starts throwing flyers. [/QUOTE]
