Having decided that Staline made the brass cases for CFDA, I emailed Starline on their contact page. In just a couple of hours, I received a reply. A nice lady named Debbie Beischer replied, telling me: "Sorry we make these cases for the CFDA exclusively." Oh, well, I had to ask. If they've got an exclusive contract with CFDA, I'll have to find a work-around.
As it turns out, my metal-working son took an example piece of CFDA brass to work and after a few basic measurements, modified some .44 magnum brass to take shotgun primers. He tells me that with a 1/4 inch drill bit and a 5/16 end mill, we should be able to manufacture that primer pocket (and have it look good) on a common drill press.
A carbide end mill cost less than $30.00, and it's a one-time purchase. It should amortize quickly and last almost forever. We're cutting soft brass, after all.
This may take a little more research, but I've begun pondering mightily on the problem, and a plan is beginning to gel.
