Perhaps this depends on things like what load a person shoots and how many they shoot, whatever else, because my experience with both a 686 and 60, different trips in different years, neither would seat .357s at the end of the respective trips- and it took several hours to clean the charge holes each time. I'll never do it again (as long as my memory holds up ). I wouldn't have done it a second time if I'd remembered the outcome from the first episode beforehand.
