Lee Rifle caliber Trim Dies are designed to be used with the Lee
Deluxe Quick Trim and Value Quick Trim Case Trimmers. Each die is made
to hold the brass cases securely while the cutter is turned to ensure
that case mouths are cut square and the case is to the exact desired
length. Each die is threaded 7/8"-14 to work in all reloader presses
that accept standard reloading dies.
