The Lee Precision Conversion Kit provides all the necessary gauge-specific components to convert a Lee Load-All II press to reload 16 gauge shotshells. This comprehensive kit allows a user to quickly change their press from a different gauge and includes a die carrier, sizing ring, wad guide, shell holder, priming parts, and a crimp starter. This makes it a fast and economical way to start loading for 16 gauge without needing to purchase a second press. Please note that powder and shot bushings are not included with this kit and must be purchased separately.
