Lets you use Hornady 50 cal XTP bullets (as well as others) to load slugs for rifled barrel 12 guages.

I have had great results using home-cast slugs out of the Lyman 12 gauge mold and standard wads, but it is good that there is an "off the shelf" option that also lets you use the fine XTP bullets.
