Hopefully I'm not crapping all over your thread csdilligaf by posting my stuff. Not sure what the correct etiquette is but since you helped me with figuring out better leverage with the press knuckle I thought I would post my current progress.
Pretty happy with how well things are working so far. First dies were made from 4140. This die is A-2. A-2 is polishing up much better. Heat treated to 62 RC and then tempered back to 55. Definitely need to work out a couple things.
Next die will be modified to include:
-Smaller lead overflow port
-general reshape of slug with slightly squarer nose
-better die "plunger" I'm getting some over squeeze on the back end of the slugs that you can see me rub off each slug before I remove it from the press
