thanks DaveInsofar as the typical 19thC British .45 cal long range muzzle loading match rifle, false muzzle's weren't needed for preventing damage to the bullet. The paper patched bullets are marginally under bore size and a slip fit, loading with the weight of the rod. Nothing is needed to 'get the bullet started'. They expand to fit the rifling on firing. False muzzles were however provided by some makers - these were essentially to stop wear at the muzzle from the action of loading and cleaning rods. There were also muzzle protectors available to slip over rods and use when loading/cleaning.
