You need patches, balls (about .010 less in diameter thhan the caliber.) Commercial patches are carefully manufaturered to certain thicknesses. .015 thick should do ya.
You will need a powder measure. In a pinch, an empty cartridge case such as a 45-70 works well. A 45-70 casse will hold around 75 grains of powder. A 30-30 will hold around 40 grains.
You will need a safe container for the powder. Horn, flash etc.
a ram rod. Some factory ramrods are meant to be used only in a pinch and are poor quality. A stoudt ram rod is some times called a range rod, because it is used most frequestly at the rannge.
A short ball starter. Cheap to buy, easy to make.
An extra flint or two, a ball puller, cleaning jag,, short screw driver, pliers, pan primer flask make things easier. Then you will need a tackle box or Rifleman's bag to carry it all.
