Joey,
I don't visit this site that often, so late to the party. My last new build was tuned and tested for ammo by the builder. He said the barrel was broke in when I got it. I will say, that the rifle has never been shot more than a cards worth of ammo between cleaning by me. Which is to say, I agree with Wilbur.
If Don does not shoot a bunch of rounds through it, I would shoot 25 or so, clean and repeat. After 50 to 75 rounds. I would just clean between a cards worth. Not saying everyone will agree with that, just saying that is how I broke in all my new aftermarket 10/22 barrels.
I just counted my tuner and ammo testing sheets and I believe 710 rounds were fired through my rifle before it was shipped. I would say the barrel was broke in and agree with the builder. Hope this helps. Best of luck with the new rifle. New rifles are fun!!
Best regards,
Scott
