Why are you so worried about your throat?
They erode, no matter how often you scrape it, polish it or any other thing you do to it, it WILL get larger and longer. How it looks has NO impact on accuracy, if it's dull that's because it has eroded and has haze cracking, normal wear, nothing more. What kills accuracy is how FAR it has eroded DOWN the barrel, increasing the LENGTH to the origin of the rifling.
How much has your velocity dropped with the SAME load over the last 8 years?
If it is substantial, say 150-200fps, then yes, your throat is eroded and accuracy will gradually lessen off, how much you ask, no body knows, but barrels just don't go 'bad' overnight.
BTW, the carbon ring is a good thing, it keeps your bullets straight!
I shoot comp in 200 round strings, never do I clean after a 60+ round match, never!!
I've seen more barrels ruined by excessive cleaning than I have from excessive shooting!!
Cheers.

I am worried about the throat mainly because of the rate of fouling. Only a few shots baked it in enough that it was hell to get it out. The barrel is shooting pretty much how it always has accuracy and speed wise.
