Here is the die. I got as close to .431 as I could without going over. This is a bullet of range scrap air around BHn 12. I can get a little bigger but fear is going over. Alloy changes will make a difference, harder alloy likely springing back some to give larger bullets.
I need to make a push rod then will get it on the way to you.
