I've never encountered a "shot out" ar-15 barrel in 5.56. Some friends say they've had competition guns where the groups open unacceptably and they replace them, but they are thousands of rounds into them.

Also, in a SHTF scenario, I'm going to use what ever is available, as long as it is available, until something better comes along.

Truth is in an EOTWAWKI event, any of us will be lucky to be around long enough to shoot out an AR barrel.

And finally, if you're not sitting on enough ammo to shoot your barrel out, then this isn't relevant to you anyway.

3,000 rounds per 5.56 rifle/barrel (you can stockpile barrels as well) seems a good target.

I gotta go, I'm behind on reloading by my own account.
