I'm going to do some research on this. I have never heard of the carbon ring until reading on here. Sounds like some barrels/guys get it and some don't.Apparently the barrels I get are magical because I don’t get carbon rings, or if I do they do not cause any issues, and they all maintain the same 20-30 round group size from 100’ish rounds to nearly the end of the barrels life. My barrels last as long or longer than they did when I cleaned religiously.
I will note this gun was just in the smith shop getting the stock put on and cerakote. The smith said there was significant firecracking in the barrel. I don't have a borescope so I cannot confirm. But I can't imagine this gun has more than 200 rounds through it. It belonged to my grandpas lifelong hunting partner who passed it down to my dad when he passed a few years ago. Dad didn't need it and gave it to me. I would be surprised if there is more than 200 rounds down the barrel.
I understand the theory of overbore and "hot loads" leading to cracking and erosion. But a 300wsm shooting 180's in factory loads is far from what I would consider overbore or a hot load. Maybe I will have to get a borescope and check it out.
