Unprimed brass for the 204 is hard to find right now. The brass is in hot demand as loaded ammunition. I bought 200 rounds of Hornady ammo, 100 of each (32 and 40 grain) so Im ready to reload once fired brass.
Checking the price of 20 caliber bullets and the price of unprimed brass, its cheaper to buy the loaded factory ammo at this time. No one can buy the powder that makes the 204 as fast as it is in factory rounds anyway.
