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?
