Boggles my mind.
6mm Lee Navy is a one-off cartridge, it is commonly said that .220 Swift is a development and its brass has been used to kluge up ammo. But if you do that, you would be better served with 6mm Cobra.

RCC makes brass at $5.85 EACH. I think lathe turned from brass bar stock.

Buffalo Arms only wants $1.89 because they form it from .25-06. As I recall, this calls for a hydraulic press and lathe.

Dies are $110.
