I shoot until I start to suspect a change in accuracy.
Then I clean using a Dewey rod, nylon brush, Hoppe's. Scrub about 20 passes from chamber to muzzle. Jag with clean patch and repeat with clean patches until no color remains on patch.
I sometimes check my cold bore afterwards but after years of the same routine I'm confident of CCB after cleaning this way. I hunt with my gear so I clean considering the CCB shot as my priority. Not too squeeky clean but not too badly fouled either.
