For most of the length of the barrel it does burn cleaner.. it is that burn zone right under the sabot where the ring normally builds up. Some people say the temperature of the primer makes a big difference.

I can only tell you what I do and it seems to work..
I use an old Remington primer - do not think it is even available any longer - it is a Remington 209-4 - built for 410 shotguns. And the other primer I use is the Winchester triple seven primer - both of these are much cooler than a regular Winchester.
So if I could suggest find the coolest 209 you can and try that....

Winchester 209ML ........................221 f.p.s.
Winchester 209 Triple Seven ML.....244 f.p.s.
Remington 209 Kleanbore ML ........318 f.p.s.
Std. Winchester No. 209A ..............336 f.p.s.

You are exactly right... but the physics of the two are a lot different. Another thing and this is just my own personal opinion, the 'crud ring' may also be related to what is in the bore... The Temp and the Pressure are reacting and crystalizing with something. I have no idea what... All I know is for some reason I really feel no pain from shooting T7. I even shoot it with PRB's and it works well with very little residue left in the barrel.
