In my cap and ball shooting box are two 9" long hardwood dowels. One is 5/16" diameter for the .36s, and the other is 3/8" for the .44s.
I epoxied a fired cartridge case on each end, to keep from splitting the wood when tapping out a stuck ball: .32 ACP for the 5/16 and .40 S&W for the 3/8.
A cheap fix, and effective for tapping out a stuck ball or wad.
