Cut patches, on a thread, then dipped in melted (Track's ) mink oil then squeezed out and kept in a tin or small plastic 'tin' in the bag is a good way of carrying these. A properly 'finished' patched-ball, bullet- board is another way of carrying them, ready for loading.
In my .32, using mink oil and .320" balls with .020" patches - really easy loading all day and no fouling buildup in the bore at all, seriously, easy loading & no wiping.
