So I went down in the basement and played with the mill.
I opened up a .40 caliber mould at the base to make it patched to .403" DD .300" long.
.404" patched is the largest diameter that will fit in my fired .40-65 case.
It has a very tight chamber with a 4º/1º-30" funnel compound lead.
I have 50 cast and will shoot them tomorrow to see how they fly.
And I made some cherries for the .44 but I have to harden them yet and find some good cast iron to make some blocks.
This will be a good winter project.
