The question is "how would you knowI have a high volume AK and am attempting to get an idea when the barrel is worn out. It is still accurate to 100 yards but haven't had it passed 100 yards in two years.
"Cut Off Range Complex"....Also a sponsor of this board. His revolving ad is at the top of the pages.Yes, I would use keyholing to determine that the bullet is not stabilized, as well as accuracy.
Currently the 18k round barrel is fine to 100yds. In the past I shot it out to 425yds at the old fts range on their coyote target with no issues, also no issues on their hog target at 300 yds. At some point I will make it down there again (under new ownership, Cutoff Shooting something) and test it at longer distance to see if accuracy has diminished
Tell on. What specifically would make accuracy diminish then ?Accuracy might diminish prior to throat erosion, gas port erosion could also occur abusing the rifle during cycling.
Gotcha. What causes that ?Inability to constantly stablize the projectile
LOL.Load changes, projectile changes, harmonic changes, crown damage, firecracking, throat erosion
