I hope this is the correct forum.
I have a surplus of .357 mag cases and a shortage of .38 special cases. So I'd like to shorten some of the .357 brass.
I'm looking for an economical way to cut the long cases. I don't own a lathe and can't justify a special machine.
My best guess is to make a mandrel, spin the cases in my drill press with a center in a vise to support the case heads, and use a hack saw to cut them to rough length. I'd set up a height block for the saw. Then trim the cases to length.
...I can put a drill chuck on my radial arm saw's arbor, but it would be complicated rigging up an outboard support.
Any better suggestions will be appreciated.
