PCC barrel life

[Nicolas.]

What is the expected barrel life on a PCC barrel ?

If you're referring to "acceptable accuracy" life for a 9mm AR barrel that you'll use in semi-auto?  I don't know anyone who has ever worn one out.  I do know of several 9mm AR barrels with upwards of 20k mostly full auto rounds through them that are still good to go.

Coated Bullets would probably last a very long time.

I had a 3 gallon bucket of spent primers through a Craddock 9mm barrel (and some went through my STI OPEN gun) before I replaced it with a BSF. I did it solely for weight and it was still grouping great.
