A sub topic was also brought up again by Mule Deer I believe. That its not necessary to clean some barrels all that often.
I sort of knew this from way back but the reminder got me to try it again. So some of my best shooting rifles don't have their barrels cleaned at all.
Of course if a rifle throws a shot fouling is suspect and I clean that one.
As to the powders that help clean I am all for it but I don't use much of them.
The load I used for the 6mm Remington International where I shot it over 130 times in one day at the full course Free Rifle matches used Sierra bullets and IMR's 3031. That barrel is worn out now and I have not tested the new barrel that much.
