Those are really nice to see.
In the 10.4mm what exactly are those disc’s with raised centers on top row right side. If they are showing them spun into a cup, aren’t they fitted to the board in backwards order?

Pete, the primer pocket!

Great boards! Thanks for sharing.

OK So if I’m understanding this
1st a flat disc,

then it’s coned shaped,

then through four stages the outer edges are again flattened leaving a primer pocket size post & a rimmed / thicker outer edge

then this is cupped & drawn into the case?

So am I understanding this process correctly?

If they can draw / form a rimmed case I’d think it would certainly be easy enough to form a primer pocket in one of the cupping stages?

Anyone have any thoughts my questions on the 10.4 board?
