Saliva and then only when the last shot was harder to ram home , if you find that you have to swab all the time then something is amiss ( unless shooting super tight benchrest loads ) your patch ball combo is too tight , patch lube no good , too much fowling etc. as Stumpkiller posted above a saliva patch every 10 shots should be all that is needed , in fact swabbing too much is one of the main causes of miss fires on the line , slimmy crud building up in the breech areas and blocking up the ignition path . :thumbsup:
