I am in the middle of the road on this topic. My barrel cleaning, has evolved over the years, as I nearly scrapped a very good barrel, a long time ago, due to build up in the throat. Now, our cleaning supplies and technical cleaners, and actual techniques have gotten much better. Back then, Hoppes 9 was the norm, and it wouldn't remove copper, and wasn't the best for carbon either. So ignorance was bliss in that situation, and I nearly lost a barrel. Then came shooters choice, sweets, etc, and JB more cleaner!
Since the evolution of our modern cleaners, I've found a happy medium, and am in the camp of shoot the rifle, and monitor your shot count, and watch your groups. When they start to open, a cleaning is in order. OVERCLEANING, is as bad as any of it, because it strips the barrel, then it takes a few, or more for it to settle back down.
Bore cameras, can be a good thing, or a bad thing. It can cause people to overclean, or to think there barrels are junk, depending on the individual interpreting what they are seeing. Also remember, and I know this to be true, cleaning causes more damage, in some cases then not.
Our modern propellants leave a carbon signature, more so then the the older powders, and left unkempt, can cause problems. Lots of variables. Magnums need more cleaning, then non magnums, more powder, more carbon.
Again, in in the middle, clean when groups open, fire a few foulers, but clean carefully, watch the crown.
Peace out, 7stw
