The Hornaday Lock-N-Load AP press is a professional-grade, auto indexing 5-station progressive press that features the patented Lock-N-Load bushing system. This system allows you to switch dies from one caliber to another, or change out die stations and begin reloading again in seconds. Once set, dies never need readjusting. The bushing locks standard 7/8 in. x 14 dies rock-solid in perfect alignment. Plus, Lock-N-Load uses a full-size powder measure that can be reset to another charge or powder with the push of a button. The unique inserts can be preset to the charge you use with the caliber you are loading, making this the most flexible and economical powder system available for progressive presses.
