This is a discussion on how many rounds before barrel replace? within the The M14 forums, part of the M14 M1A Forum category; Just curious, how many rounds can you fire out of a new Springfield Scout barrel before it needs to be replaced?...
Is your barrel chromemoly, chromelined, stainless? Barrel wear can be dependent on how the rifle is shot (many rounds at a time, just a few rounds shot slowly), how it is cleaned and how often, what ammo is used (powders, jacket materials, casings) and how the rifle is stored after shooting.
Also what kind of shooting are you doing and what range? Acceptable CQB or plinking accuracy may be different than that desired by a match shooter.
I remember reading that for every thousand rounds that are shot there is .100 wear at the barrel throat, which most shooters use as a guide for barrel wear. I have, however, seen barrels that had some significant throat erosion that still had very acceptable accuracy.
Most likely your barrel will have acceptable accuracy for years of shooting.

assuming a non chrome lined barrel. depending on care, maintenance,abuse you could kill the barrel in less than a thousand rounds. assuming you treat it properly i would expect you to see acceptable accuracy through 5000rnds.
The Scout rifle is not a target rifle so acceptable accuracy could run upwards of 9000 rounds.
Match grade rifles tend to have peak accuracy to about 6000 rounds but will still have reasonable accuracy (not match accuracy) to about 9000 rounds.
Chrome lined barrels will usually shoot well for a good 3000 rounds more.
Acceptable accuracy depends on your needs and expectations.
I have an old M1 Garand with its original unlined barrel the TE is 7+-, ME lets just say it will almost swallow the Bullet
Match accurate she is not. She still exceeds my Expectations and will always hit a Paper plate at 200 & 300 yards with Greek Surplus
It is my Hunting Rifle.
I figure she has had Well Over 5000 pills down her throat
Avoid corrosive-primer ammo. Clean every time you shoot, if possible. Stroke it out with JB compound once in a while to cut the copper fouling. Heck, toothpaste works, chase with Hoppe's. And keep the chamber shiny clean. That's all.
