Might already have been said so I apologize if so. I didn't want to read all three pages. I used to wipe after every shot, every 2nd or third if I was being lazy. Then I switched two things. One, I started using real black, which of course fouls a lot more than Pyrodex or Black MZ (mediocre substitute made by Aliant that is only half the cost of Pyrodex. worth the difference for plinking, I didn't get consistent enough results for match shooting but then I don't shoot matches. ) The other thing I did was start using Moose Milk, the version I use is similar to whats been called MAP, but no Peroxide. Its 1 part water soluble cutting oil, one part Murphy's Oil Soap and I think three parts water, some use Alcohol and water.
My result was consistency shot to shot without wiping. No significant bore fouling as each load with a patch dampened with this wipes the bore for me. Its as consistent at my level of shooting as any other system I've tried, and since I'm relatively lazy its easier.
