With all the conflicting info, variables in ammo/barrel types/rate of fire, etc, I'd be interested in knowing anyone's personal experiences shooting barrels to the end of their service lives. Any details you can share would be great.
For example, "I shot my dept issued patrol rifle's barrel out by putting 3k rds per year on it for 5 years. It was a Colt 6920 that was only fired on semi, and it was rebuilt once it wouldn't hold 3MOA with duty ammo. Duty ammo was 55gr Gold Dot. "
While I fired 9k rds last year, I put maybe 2k on any one weapon, making it unlikely that I'll push any one weapon past 15k soon. Personal accuracy standards are 1.5MOA max for precision semi-autos and 3 MOA max for regular semi-autos when averaging five 5-shot groups. (Not much point shooting anything less accurate than that.)
