Redding offers top quality case forming dies to make 219 Zipper from 30-30 brass. They aren't cheap but are available for less than list price from
Graf,
Sinclair and others.
Surprisingly, considering that they aren't usually as carefully made, the equivalent RCBS case forming dies available from
Huntington are higher priced than those Redding offers.
Cheaper than this is to simply scrounge. 219 Zipper brass (and ammunition), though not currently manufactured, is available, if not common. I suggest looking in long established gun shops- you never know 'till you ask.
BTW, if you have a good rifle in this chambering, you'll be pleasantly surprised at the accuracy possible. While I've never seen groups that would excite interest at a benchrest match, many of the fine old single shots that were reworked for this cartridge from the late 1930's through the 1950's are capable of consistently shooting 5 shot groups in the low 3's or high 2's in favorable conditions. IMR 4320 is a good powder choice to start with.
