Talking about black powder die's is there a optimum size or does it depend on how big your press is, I want to turn one as I have some 101 mm dia 10 mm thick walled tube with a internal dai of 82 mm, to much?
A few I've seen are around 75 mm plungers and downwards would it be unreasonable to have a plunger size of 60mm diameter ?


I would guess it mainly boils down to how big your tools is.


The PSI or N/m^2 is the most important factor along with minor factors of ensuring that any moisture can escape during pressing (to large a dia would hinder this) and how are the pucks going to be broken up.
