Wayne Goerres had this one made, or maybe he made it himself I cant remember. I think the basic idea is you just need a machine shop to bore a hole into a piece of metal the diameter you are wanting your cases sized to. If those brass cases are tough you would might want to have several dies made and do it in gradual increments as not to crush the brass I would think. Its 2" in diameter and 3.5" long. Which I think is perfect as it being slightly longer than the case protects the mouth when resizing. I then flip the die upside down and just press it out with a 3/4" wood dowel cut to just long enough to fit under the arbor press. It resizes them from .940 -/+ down to .924 in one press.

Its simple and works, ive seen some smaller versions of a resizing die like this made back in the day for 12 and 16 ga I think Lyman made them? You could probably have it fluted or made 1.5" in diameter as its quiet hefty if you drop it on your foot thats a trip to the ER :rotf:.

Actually the diameter lets it sit in a arbor press like in the last picture if it was made smaller in diameter youd need something brace it. I have wondered if aluminum could be used to make a lighter version.

my resizing die is just like yours milt...wayne gorez gave me the specs on it a friend done the work on it...works great...in one step....charlie
