1.) I load 12 ga for my vintage guns at 6700-6900 psi. It is my ( possibly incorrect ) understanding that appropriate pressure levels vary per gauge. I.e. 9000 psi in a 12 isn't the same as 9000 psi in a 20 due to the difference in diameter. If my belief that 7000 psi is appropriate and 8000 is a max for my vintage 12 ga. What would be comparable pressures in a 16 ga
2.) anyone have 2 9/16 recipes using green dot powder? I have many options in hulls but prefer to stick to the powder I have if possible.
