I, too, have the RCBS dies but they are not essential. Brass shells can be completely reloaded with expedient tools.
Depriming goes a bit better with a LEE depriming punch
RE-priming can be done with a copper pipe punch over a piece of flat metal
Use any Blackpowder measure for powder
wads can be inserted by hand, and seated with a wooden dowel
shot can be measured with a LEE shot measure (about$5!) or just use the same measure as for powder
The over shot card can be glued in with Elmer's glue
Short of wads? Use a 3/4 inch punch from any hardware or Tandy store and bang away. Any firm cardboard, like family pack cereal boxes get my attention. A stack of wads knocked out of pulp egg cartons will do for cushion wads if you can't wait for your supply to arrive from Circle Fly. How about 1/8" Cork gasket material from the carparts supplier?
Crimping the mouth is unneccessary. Re-sizing is unneccessary.
Plastic can be used as well! I prefer R-P RTS or GUN CLUB. Use a field wad to allow more room for Blackpowder.
There is plenty of advice on Cascity or The Open Range
