Would you mind sharing a picture? I have an idea of what you did (bedding a bullet in epoxy putty on the seating stem to create more contact area?)
I'm about fed up with my Forster seating die doing this on uncompressed loads with 'normal' neck tension, and would like to try this before getting a different seating die.
I will try to remember to upload a pic. I used a type of plumbers puddy so it would hold the shape, rolled up a little ball and dropped it into the seating stem. I then took my bullet and stuffed it in tight and cleaned around the base. After that I pulled the bullet and wiped it off and then wet it slightly and put it in and spun it in the putty to smooth it out, being careful to keep it straight. I pulled the bullet once the left over putty on the table started to harden a little and waited until the next day to use it and it worked perfectly. I did sand the inside of the stem a little to ensure the putty would stick.
