Description
The L.E. Wilson 223 Remington Bushing Neck Sizing Die (SND-223R) is a hand die built for reloaders who care about repeatable neck tension. Instead of relying on a fixed neck diameter or a conventional expander ball, it uses interchangeable sizing bushings that work the outside of the case neck. Swap a bushing and you change how much tension your brass holds on the bullet, which is the kind of control that separates good ammo from great ammo. Bushings are sold separately, so you can match the exact diameter your loaded rounds call for.
Why the SND-223R Earns a Spot on the Bench
Because this die eliminates the conventional expander, it improves neck concentricity and reduces how hard your brass gets worked. Less stretching and pulling on every cycle means your cases simply last longer. The die sizes the neck to about 3/16 inch from the case mouth and leaves the case in its fire-formed condition, so the body and shoulder stay true to your chamber. This is a neck-only die, so it does not touch the case body.
Running the 223 Remington Bushing Neck Die
This is an arbor press style hand die, not a die that threads into a standard 7/8-14 press. You'll want an arbor press and a neck die base to run it, both sold separately. The payoff is feel and feedback. You can sense exactly how much the case is being sized, which is why benchrest and precision crowd reaches for Wilson tooling. It accepts L.E. Wilson and Redding neck bushings, giving you plenty of range to tune.
Built the Wilson Way
L.E. Wilson has been a family-owned operation since 1927, and the stainless steel construction here is made in the U.S.A. to very tight tolerances. To pick your bushing, measure the outside neck diameter of a loaded round and go roughly .002 to .003 inch smaller. It's a simple system that rewards attention to detail with consistent, accurate handloads.

Frequently Asked Questions
Do I need a bushing to use the 223 Remington bushing neck sizing die?
Yes. Bushings are sold separately so you can match the exact neck tension your load calls for. To pick the right size, measure the outside neck diameter of a loaded round and choose a bushing roughly .002 to .003 inch smaller. The die accepts both L.E. Wilson and Redding neck bushings.
Does this die work in a standard reloading press?
No. The SND-223R is a hand die designed for use with an arbor press, not a threaded 7/8-14 press. You'll need an arbor press and a neck die base to run it, both sold separately. If you want something that threads into a conventional press, Wilson's bushing full-length die is a different product.
Does the bushing neck sizing die size the whole case?
No, it only sizes the neck, working about 3/16 inch down from the case mouth. It leaves the case body and shoulder in their fire-formed condition, which is ideal for brass dedicated to one chamber. For sizing the body and shoulder too, you'd want a full-length bushing die instead.
Why use a bushing die instead of a standard sizing die?
A bushing die removes the conventional expander ball from the equation, which improves neck concentricity and reduces how much the brass gets worked on each cycle. That translates to straighter necks, more consistent tension, and longer case life. Swapping bushings also lets you tune neck tension as you develop loads.
