L.E. Wilson has been making precision reloading tools for over 80 years. The L.E. Wilson Neck Sizing Bushing allows the reloader to custom fit the L.E. Wilson Neck Sizer Die to any brass and bullet combination helping to ensure top accuracy. Since brass has a tendency to "spring-back" after sizing, it is very important to take the correct measurement resulting in consistent .001" to .002" inch of grip between the case neck and the bullet. Consistent neck tension is a key factor in the most accurate reloads possible.Bushings will freely interchange in all Wilson bushing type neck sizing dies.
To Determine Bushing Size, measure the outside neck diameter of a loaded cartridge with a precision micrometer. From this measurement subtract .002" to .003", to allow for brass spring back and bullet tension.
By selecting the correct bushing you can provide just the right amount of neck tension to properly hold the bullet without excessive resizing.
