How are you going to know if you have a good barrel if you don't shoot it? Barrels are consumable IMO just like welding rod. You can't become a good wrlder without burning some sticks.
No worries, all my rigs have a half inch guarantee. I'm sure its all good.
All I can say is you haven't spent much time in a dog town. On an active day you'll be hard pressed to keep a barrel cool on multiple rifles.
