Cosmoline: You are not the first MLer to think to try those plastic shoes to hold a RB instead of a patch. What we all found, the hard way, was that in addition to having to clean Lead out of our barrels, as well as powder residue, we also had to clean out PLASTIC residue. That involves other solvents( we didn't all have the correct solvents, and had to search gun stores to find a bottle of the stuff) to dissolve and remove the plastic.
By the time you get done buying all the extras that allow you to use the plastic shoes, You realize you have defeated one of the purposes that attracted you to ML rifles in the first place--- CHEAP FUN! You still had fun, of course, but it now was no longer " Cheap ". And cleaning took twice the time and more to get the barrel clean again. Most of us either gave those shoes to someone in the club, or shot up the bag we bought and went back to cloth patches and spit to recoup our lost " mad money ".
There are always two ways to learn things in this sport: listening to others and learning from their mistakes; and making all your own mistakes. Its your choice.
