The Lee Pro 1000 Shell Plate is made in various numbers used for different calibers. This shell plate is the ideal choice for the .32 H&R Magnum, .32 Smith & Wesson, .380 Auto, .222, .223, and many other cases of a similar type. Used with the Lee Pro 1000 press, this shell plate makes changing calibers easier and quicker. An advantage of using this shell plate is that no tools are needed to change from one shell plate to another. The manufacturer notes that the Primer Attachment is required to change to a different caliber with a different size primer.
