At a rendezvous event I visited last summer, this discussion came up. I was told that among reenactors and members of black powder clubs have come up with a rule when giving demonstrations or performing battles for the public. Their rule states simply that the ramrod will not be used at all. Powder and loose wadding is dropped into the barrel, one or two firm taps of musket butt onto the ground and the powder/wadding inside settles enough to catch the spark and make a nice noise.
It seemed to work quite well for these people, and I do not recall seeing a ramrod used at all.
