Another common new guy mistake is not getting an unbreakable cleaning rod of brass or steel (some like delrin) with a bore protector. Starting the cleaning with a dry patch in a fouled bore often ends with a stuck patch. Always start cleaning with a very wet patch.
The cleaning jag should be brass with a steel machine screw to thread into the cleaning rod.
