Patched round ball shooters may experiment with using different patch thicknesses, or RB diameters, or exhaust their supply of either component. I expect that most of these shooters have [tried??] jury-rigging loads by using more than one patch when loading - that is, double patching thinner cloth patches to emulate the thicker patch they prefer or exhausted.
As best you can, patched RB shooters, how does such jury-rigging effect accuracy, consistency, and perhaps velocity?
