Hornady Lock-N-Load Shell Plate #57 Features The Hornady Lock-N-Load Shell Plate #57 is machined from steel to hold up to the repeated cycling of a progressive reloading press without wearing out of spec. Each shell plate is precision sized to its designated caliber so that cases index correctly at every station from sizing and priming through powder charge and seating. Reliable indexing is critical on a progressive press since a poorly fitted plate can cause misfeeds or inconsistent case alignment that slow down a reloading session. Hornady designs every shell plate in the Lock-N-Load line to the same standard of fit and finish so reloaders can trust the press to run smoothly. Switching calibers on a Lock-N-Load AP press is as simple as swapping in the correct shell plate making it easy for reloaders to support multiple cartridges without buying a second press. This Shell Plate #57 also works on Hornady s older Projector Press extending its usefulness to reloaders running earlier equipment. Because the plate is a wear item that sees constant contact with brass having a spare or caliber-specific plate on hand keeps a reloading bench ready to go. The Hornady Lock-N-Load Shell Plate #57 is available for sale at GrabAGun for reloaders adding a new caliber to their progressive press setup.
