I've shot as many as 300-400 rounds per day, then disassemble and drop all components in a Harbor Freight sonic cleaner and all have come out sparkling clean. However the expansion chamber sleeve was locked in and could not be removed. This hasn't posed a problem as the main tube with sleeve inside still cleaned up nicely in the sonic cleaner.How many shots between suppressor cleanings?
I have a friend who has just kept shooting 1000's of rounds year after year and his cans have locked up so that cones can not be removed. He shoots 20000+ rounds per year and has several cans so I have no clue how many each can has accumulated. He finally retired some of his cans this season. They had accumulated some serious carbon as evidenced by the total weight of the can.
