The L.E. Wilson Bushing Neck Sizer Die is the perfect die for the reloader looking to squeeze every ounce of accuracy out of their handloads. These dies are available in corrosion resistant, long wearing Stainless Steel in most popular calibers. Bushing Neck Sizer Dies feature interchangeable bushings to size the outside of the case neck to 3/16" from the case mouth. This allows for total control as to the amount of neck sizing each case receives. Simply change the bushing to increase or decrease the neck-tension on the bullet. (Bushing sold separately.) These are a hand-die design meaning that reloaders must use an arbor press or a mallet to size each case these dies will not work on a conventional press using threaded dies.
