The Lee Loader for shotgun shells were made by Lee Custom Engineering. For the whole story, read Richard Lee's article in Handloaders Digest, 17 th. ed. Lee Custom Engineering has been out of business since 1988, and Lee Precision does not make parts for those tools. We have no plans in bringing this tool in to regular production.
Instructions are attached for review.
To help identify gauge, we suggest to insert a shot shell into sizing die. A 12 gauge will be tight, a 20 gauge will make no contact
