SGD,
If you want to be "thrifty" you can get one flat bullet punch that fits the smallest die you use and use it on all the bullets, but I don't recommend that. I'm not sure of the diameters of the punches, when I ordered the dies, I ordered a corresponding punch flat topped punch. When Star was in business, they were great, but truthfully, magmas dies seem every bit as good as Stars. You can contact Magma for the tolerances.
