The L.E. Wilson Steel Neck Sizer Die Bushing for .308 is a precision reloading accessory engineered for shooters who demand consistency and control over neck tension. If you're handloading for accuracy—whether you're fine-tuning match rounds for competition or optimizing hunting loads—the right neck bushing is essential to uniform case prep and bullet grip. L.E. Wilson's hardened stainless steel bushings are made in .001" increments, giving you the granular sizing control that generic one-size-fits-all dies can't offer.
L.E. Wilson neck bushings work inside compatible L.E. Wilson neck sizer dies and are reamed with a .003" taper, so the bushing contacts the case neck in the middle section. This design lets you fine-tune sizing pressure without dropping to the next smaller bushing—a real advantage when you're chasing that sweet spot between consistent neck tension and minimal work-hardening. The marked size on the bushing refers to its middle diameter; you can even flip it over (markings facing the case) to achieve slightly tighter sizing if brass has hardened and spring-back becomes an issue.
Sizing neck tension directly affects bullet runout, concentricity, and ultimately accuracy. With L.E. Wilson's .001" increments, you can dial in the exact bushing diameter your loads need, rather than settling for the closest available size. These bushings are made to specs comparable to Redding bushings but are not interchangeable with Forster or RCBS dies, so confirm die compatibility before ordering.

Frequently Asked Questions
Will this bushing fit my Forster or RCBS neck sizer die?
No. L.E. Wilson neck bushings are not interchangeable with Forster or RCBS dies. Confirm that your neck sizer die is an L.E. Wilson product before ordering.
How do I select the correct bushing size for my .308 loads?
There are two methods: (1) Measure the outside neck diameter of your loaded cartridge and subtract .002" to .003" to allow for brass spring-back and correct neck tension. (2) Alternatively, measure your case neck wall thickness, multiply by two, add your bullet diameter, and subtract .002" to .003". L.E. Wilson's .001" increments let you fine-tune the fit precisely.
Can I flip the bushing over for a tighter fit?
Yes. Reversing the bushing so the markings face toward the case achieves slightly tighter sizing. This is useful if your brass has work-hardened and is springing back excessively, or for fine-tuning neck tension without stepping down to the next smaller bushing size.
