[QUOTE=RonnieMilsurp;5608560]I do not. What's the potential problem with just firing it with a charge of BP and a bullet?
cant think of one ....348 winchester brass is some of the toughest you will find
mark the base or cut a little nick in the rim that lets you orient the case in the chamber so the bulged side is down and straight side up
I made a couple hundred 348 cases over to 45/75 without hassles - pretty much followed Wallaces' system - step by step slowly with expanding dies - I annealed twice - first time before I started then again towards the end - made the expanders out of some high tensile bolts - I found a match up for the thread in a RCBS die body then turned the bolts in the lathe - you could do it in a drill press ok - make em with a gentle taper so the end is just small enough to enter the case neck without swelling it - works like a pilot and keeps things all straight.
