Now that I've posted my "original" "ingenious" solution, I come to find out it's a known problem throughout Hornady users, I'm just the last to figure it out. Seem like, pennies, nickels, dimes and quarters are the common solution. I didn't want to raise the "dead bottom" too much as it might interfere with the prawls not getting a full down stroke, but evidently there's quite a lot of room between full progression and the bottom.
At least some people thought my solution was better than throwing money at it.
