The harbor freight set goes for 9.99.
Three punches in the set will work. 5/16 for .31, 3/8 for .36 and 7/16 for .44, although the 7/16 wads for the .44 are a tiny bit small for the chamber. I never tried the half inch punch but it probably works pretty well in a ROA.
These punches are best used in a drill press but they do work with a mallet.
