Update- I finally got another opinion from a different gunsmith. As someone said earlier and my gunsmith verified, it looks like the lands were not fully removed when the chamber was cut.
I called Ruger today and explained everything. They wanted to check it out and sent me a shipping label. I got it boxed up and shipped this afternoon. Since we’re both in NC they should have it in a day or so. Hopefully they can get the chamber corrected the first time and it’s still as accurate as it was with the bad chamber.
